But I always look at my V6 funny, and I've never had a...oh, wait, I do have a headgasket problem. I'll have to stop doing that.
Thanks Grant, I'll be sure to have a chat with my machinist about clearances before I do anything.

I'd planned to leave the intake valve sizes alone, and the heads unported for the most part. The Alfa competition code seems to place an unreasonably high penalty on bigger valves and head porting, at least at first glance. I had intended to get a high quality valve-job, some better flowing valves a...

Thanks for the info. You didn't by any chance measure the change in combustion chamber volume, and calculate the new static compression ratio did you? So far the only data I have is Jim K's statement about his 3.0l. The 2.5's lower swept volume should give a lower compression number, but it has a sm...

I've found an old post where Jim K. says that he shaved 1.6mm off of his 3.0 heads to get an 11:1 compression ratio. Does anyone know if this is the upper limit for removing material from the 2.5 head? Has anyone done more? Does it start to have a negative impact on flow and combustion as the chambe...

should I shave my head?
No, not that head, I already did that! :wink: I have a 2.5L engine in my gtv6 racecar project. I suspect that it has at least one head gasket leak. It seems to be a small one, slightly pressurising the cooling system, but it's a 9 hour tow to the track and I don't want to take any chances, so the he...

2.5l flow numbers
Does anyone have flow numbers for a stock 2.5L head? Also, are the 2.5l intake runners the correct size for the stock 2.5l intake port? I know they're undersized for the 3.0l, but the 2.5l should be correct, right?
Thanks
Graham
