Thanks for the replies. It helps to pinpoint the fact its all in the type of headwork done. After looking around at some kits I thought maybe using the 468 eagle kit with the Ibeams for the bottom end, the xe274h comp kit, comp 1.5 rollertip rockers, felpro gasket kit, mod the quad, and intake manifold to match the headwork. The problem is to what degree of modification to the heads is required given that parts list? 3angle valve job, new valve guides, new ss valves 2.11/1.77 and how much porting and smoothing of the intake and exhaust runners are nessary. How do you know if you send them out to be reworked your not being ripped off? I couldnt tell a good job from bad job. I hear all these flow rates talked about, but it all seems kinda greek to me..Is using a 468 kit gonna jump my compression just my increased cids? Do I need to mill the heads any further? looking for 9.5 to 1 comp.....?
