their stock y8...though I'm contemplating going 1mm oversize....prolly not though
...I noticed new oem valves don't have the built up deposits on the exhaust valves, so I polished it off...maybe I'll have them coated when I'm finished to help combat heat
heres a couple of shats of the y8 and z6 in comparison..

Well I only got a couple of hours to spend on the head this weekend....got 2 intake and 2 exh ports prepped and a total of 3 comb chambers....of note the deposits on some of the exh valves is very thick....I'm including a pic with a shot of a clean exh valve an one with deposits I buffed them both to show the contrast in color....

how is a dremmel not powerfull enough? what kind of dremel do u have?

plus your not supposed to grind the snot out of it but take your time..., and you dont even need that powerful of a tool for that, this is aluminum after all.

All i am saying is that all of the performance shops ive been to dont use a dremel to port. They use something with a lil more power. You can go slower with a bigger bit and take a lot more out than you can going faster with a smaller bit. plus since the other tool's bits are larger, its easier to make the curves and such in the ports.

Well, not many of us have the same budget as a "performance shop". And, if you look at the pics a dremel will work just as well. Most of us work out of our own garages.

great photos , do any of you use a normal power drill with a flex shaft ? or do you find it a bit harsh ? i have to say i find this very inspiering , also what compound do you use to recut your valves in to the seats ? as i have never done any alloy head work hahahah i was still in the 1950s untill i got my honda

First, where'd that post go?

Okay, I'm only saying this once, and I'm not saying to hurt ANY egos....give a monkey an air powered porting tool and a head and you will get a "ported" head, maybe not what you need...but a "ported" head none-the-less...

HA...

wait i dotn get it?

all i know is that my dremel spinning at 35000 RPM is a little too ruff, i was screwing around with some metal parts when i got it and that thing DIGS IN, i went cheap and got the "on or off" one with no speeds, so i need to dig out a transformer that my buddy has so i can adjust the speed :) haahha, suckers.

but yeah... what ever tickless your pickle right?
