you need a torque wrench and the appropriate sockets.

did u find the nubs yet to tell how much has been milled? it doesnt look like too much from the pics but its hard to tell.

figure out how much it was milled and maybe mill it more how much compression you looking for. your kinda screwed on pistons for a 1.5 so all your compression is gonna be acheived from milling the head and using a z6 head gasket.

get a brass punch with the correct OD and use that to drive out the guides. measure the installed height first. warm up the head in the oven to make it a bit easier. maybe 250ish deg F or so.

drive them back in, perhaps freeze the guides first to shrink them slightly.

ive never done it before, but i dont imagine it being too hard.

head2.jpg this is the steps that you need to look at to determine how much it has been milled the first step is 1mm and the second is 2mm so take a depth mic and measure how much of the first step is missing and thats how much its been milled

minute amounts of material get removed with the guides when they get taken out. There is a specific tool also for removing the guides with an air tool. My shop heats them up on a hot plate to around 300* and he still had problems getting te KMS guides into the z6 head. Its not easy and you can ROYALY fuck a head up. Best bet is to pay the shop a 100 bucks and let them do it

looks good so far are you gonna do any porting to the head yourself or just put new guides in it and run it?

x10!

If you heat up your head too much you can warp it or cause the seats to fall out. :uh:

My shop guy freezes the guide while it's still in the head with some kind of spray and then drives it out easily. While they have it they can also acurately check the wear and replace any at a reasonable cost.
