The set that came on my Cobra crate motor, had 1/2 inch holes. The head bolts had a extended shoulder.

That's interesting, my OEM heads had the normal 302 7/16 holes

I think you can just buy the washers can't you?

thanks guys i haven't got the bolts yet and have heard of the arp bolts with the extended shoulder prob what i'll go with. i may just go with the b cam unless i can find a good deal on some 1.6 rockers and a f cam before the install. i've heard of some guys porting the irons out to a 1262 gasket can't remember right off hand which board it was. anyone heard or seen this i'm not planning this just curious.

A 1262 gasket is huge. If you're staying under 400hp NA or 500 with a power adder...you will be fine with 1250 size or close. And to port a GT40 out to a 1262 would take a long time...and you would have high iron-content in your blood and lungs afterward.

FWIW, I saw a set of Windsor Jr iron heads wickedly ported (1262 gasket)...and they had to epoxy some holes because it got too thin.

i'm working on matching these to a 1250 gasket now it's coming along okay plus i'm in no big hurry around 5 hours in them now and almost done with one head lol. i think i might just stay with the b cam since with some 1.7 rockers the lift will be almost the same as the f cam with 1.6's. that is unless anyone knows of a benefit of going with the f cam. Is there any sound difference in the 2 cams? i haven't heard the f cam but i have heard the b cam and like the sound.

Naaa. The F-cam won't sound much different... Use what you have. spend the cam/rocker money on a ZEX kit.

yeah thought bout trying a little something like that later on. would much rather have a turbo on this car sometime this year but dunno if it'll be possible money wise. prob be more like a bottom end rebuild before that comes into play.
