J-Madd Posted June 8, 2008 Report Posted June 8, 2008 0.020'' should get you close to 150 psi. You'd be fine with +4 timing and pump gas. Quote

brugal Posted June 9, 2008 Report Posted June 9, 2008 If you have a coolhead with 21 domes you wont need to mill anything. Quote
J-Madd Posted June 9, 2008 Report Posted June 9, 2008 Be sure and do a compression check before running pump gas with those. I had a motor with 180 psi with 20 cc domes/don't remember what psi 21s are supposed to be at sea level. Quote

Ya I think ur a little confused about this whole thing. Don't wanna be an ass here but instead of starting a new thread for every question try the search, it's not the best but it does work. And if you wanna do even better use this, http://www.google.com/advanced_search?hl=en Quote
