Some pics of Gude port work

[lowbuck]

I know Gude has a mixed reputation but when I saw a complete head package for $200 I figured I jump on it and she how she runs.
I've never seen pics of his work and thought others might like to have a look so here it is in all it's dirty glory. I recieved the ECU also but it doesn't make for a very interesting photo.

Throttle body, measures 2 7/16" at the mouth, haven't gotten it apart to measure the butterfly yet.

I dunno. The port job looks a little sloppy. But maybe it still flows ok.

[sl@sh]

the port looks rather normal/mild , its like porting the ports along its own shape, no reworking the roof, bowl, and short side etc... though this is juz me based on those pictures,

the mill, is rather alot.. hehehe how much was it milled?
id saye the mill = compression raise is whats gona give u the potential power gains,

[sl@sh]

to add: the texture of the portwork on the pics looks good..

[lowbuck]

The story that came with the head is that it once lived on a 13.3 sec all motor drag car in New Hampshire. The second hand knowledge is that it was in the 11.xx compression range, but I have no idea what was done to the lower end. The intake ports all look about the same, one port is a little crooked on the knife edge portion. The exhaust are almost comical. It looks like some one was setting up a "how to port" sequence photo. 1 looking like its had some work done with 2,3,4 each having progressively slightly less material removed, they are all polished smooth though. I'm not to concerned if it's not perfect. It came with fresh valves, A6 and gorrilla cams, mani, TB and ECU for $200 so if it needs a little help I'm not going to cry too much.

[sl@sh]

hey its all good... the TB alone is worth money hehe

what u can do is., refinish the head, if u say the exhaust are comical, do work on it.. im sure with little retouching u can have them looking decent..

as for the intake ports, they look right, and the rough finish is sumthing i like, use it, im sure it will run good...

on a side note, maybe u can have the gorilla cams measured by a shop.. that wud be nice....

[Levi]

that looks like they didnt do a great job in those ports. they look like there are a few nicks in there. i had horrible luck with one of their cams in my accord. i wont stand by their products whatsoever.

cutback valve guides, not good.........

current head.........

and I don't think you have a Gude TB.......

[lowbuck]

I remeber seeing something about the Gude TB's recieving the green plates more recently, I have no idea when this set-up was new. The butterfly is def not an oem piece but I won't know how big she is until I take it off and measure. Lukily I also don't really care if it's Gude, playskool or homemade, if it's ported correctly and woks I'm a happy boy
As for the cut valve guides (exh are cut also) I assume you're against them for a reliability reason. Some guesses would be valve stability at high RPM, and a short life span. Care to elaborate? The car is a low dollar auto-x, occasional drag, fun car that will see way less than 5k miles a year. So I can have a lot of fun with something that may only last 10-15k but if simply replacing valve guides would greatly extend that then I'm all for it.
Also I think the head was assembled incorrectly, I have a post over in engine building talking about the valves not retracting. Any help is appreciated. I've turned a lot of wrenches but previous valve jobs always consisted of dropping off the head at the machine shop....

[lowbuck]

BTW,
Thanks for any help or comments. I've had more cars than I care to list but mods have always been of the home spun or bolt-on variety. I knew I was taking a gamble with this head but I'm also doing a PGM-FI swap so the manifold(w/all sensors, fuel rail etc..) and PM6 ecu(socketed) is worth something to me and I'm sure the head can be straightened out with out too much $$.

[transzex]

well, in another post you mentioned the valves wiggle......not good......

Gude has been using green plates for 5 years now.......

Even as mush as I hated dealing with him, I got a killer deal on the TB and Z6 ported intake.....$50 I belive.

[lowbuck]

A little misunderstandingm the valves don't wiggle, the spring on one of exhausts valves does, but the valve is still protruding a 1/16" or so, it's like the springs are too short. All of the valves in the head are slightly off center and not quite seated, there is no cam or rocker assembly installed anymore. When I picked up the head I was more interested in looking at the port work and failed to notice the valves sticking out, the cam was installed at the time also so of course a few should have been extended, after I got home I noticed they all were to varying degrees and then removed the rockers and cam. You can see it in the combustion chamber photo.

valves wiggle = dissaster

[cagedrex]

the third pic down looks to me like the valves are bent

[lowbuck]

The post on the valve problem is over in the building section.
The valves do not wiggle.

[sl@sh]

transex could u show me more pics of ur head, looks purrty, was checkin ur build and most of the pics are pulled down.. hehe

[sql_civic]

I've done better DIY work and I'm no pro. Like I said it still might flow fine, but to me, sloopy work like this is an indication of the overall job. I'm not surprised it came with a set of bent valves.

Hope you can work this out with whomever did the work.

I really don't think the intake ports look all that different to yours Transzex. They are'nt shiny anymore, but I wouldn't expect them to be after the head has been sitting around for awhile. I'm sure if I ran a flapper wheel down them and reposted pics they would appear much closer to the freshly ported head you posted. The white spots you circled are just a little powdery aluminum corrosion that wipes right off and the black spot on the mating surface is just a piece of oily schmeg that again wipes right off. The exh ports need a little help on #2, & #4 to match perfectly but it shouldn't be too hard, even for a novice like myself.
I am interested to hear why I should be worried about the cut valve guides. Transzex said they were bad but I don't fully understand why.

I started talking about the valves here http://www.d-series.org/forums/showthread.php?t=53365 I should have guessed that the threads would merge.
I looked at the head too quickly, thought I was getting a good deal and screwed up, but it's not the end of the world.
Short of it is that he paid for new OEM Honda valves and a valve job (reciepts for close to around $500) and didn't catch the valves hanging up either since the head was never used. The intakes "look" new, the exhaust do not. As a result he has offered to purchase new valves and have them installed by a different shop since he sold me a head that was supposed to be fresh. He was pretty pissed off and freaked out by the whole thing and is getting a hold of the guy that did the work. I still wonder if it was an assembly problem. All of the int valves are bent exactly the same, the exh are all a little different, with no nicks scratches etc on any of the 16. I can't picture an engine failure that would bend all 16 valves. I've had T-belts break and seen heads after valves have dropped and they do not look like this.

Those ports are kind of sloppy. I wouldn't run that head on my car. It looks like there has been 70-80 thousanth of the surface which would put the compression between 10.6 and 10.9. The whole job could have looked better and came out better if there was more time and care put into it. It looks like there is a lot of potential there but too much of a hurry. My head is fully ported with the valve guides cut down and I don't have any problems the wiggle- they should be good for a long time.

[siregcivic]

lmfao... you should see the race head i have from gude... the ports are about twice as big as the ones in the picture... no joke.. and its shaved 80 thou.. wich makes me not want to use it until i get lower compression pistons... next time im at my friends house ill take a pic

[lemon_juice]

what he tried to circle seem as imperfections, and obviosly the one on the edge looks like a chip! not so clean, so i can see why the others look like more imperfections
