you need to look on craigslist detroit there is a guy in macomb who has every part and then some he has a banshee scrap yard in his barn and garage

I see my B.R.A.B.B. Club has gained a few members!! We need to have a meeting!!

i would just mill the head .020" for now. you can always take off .010" later. i did .020" on mine w/no problems.

what it is 0.02 converted into cc's?

[okbeast]

You can't really convert them, one is a length (kinda) and one is a volume. And aftermarket heads are cut different than just milling them smaller. Also some people will get their stock head cut and re-chambered so they will get a different 'burn' of the fuel. Do I understand it? hell no, i've just heard about it

[shanYE west]

Yep.. Very Important to get the dome rechambered. There is more to it then just shaving some off then throwing it on. The squish band needs to be corrected.

[400rednEX]

measure the squish now and cut the head down until its .040"

sounds like way to much i would probably have to run race gas

[okbeast]

No he means until the squish is at .040, not cut that much off. If you wanna cut the stock head I woudl recommend talking to someone who knows what they're doing. Pm a member named blowit, I know his company does thsi.
