Thats why i was asking, the "tech guy" at summit told me the head combos would work fine with pump gas, I have never tried figuring DCR or how a cam changes the numbers. By 350 base I meant the 350 CID with flat tops is what the combos had.....I didn't think the .120 domes would hurt me that bad with the 3.25" stroke, would 76 cc heads be better?

One of the kits, the tech guy said would put me at 9.8:1 cr
Guess I need to do some homework & get some help from you guys on figuring out what I need.
Is DCR easy to figure? how is it figured? or is there a thread on that already?
