Hey there (MadMax) I've got a pretty good set up i believe, mine is a 350sbc. It has KB120 .030 hyper flats, sitting .010 in the hole. The heads are World S/R torquers, with 170cc intake runners, on a set of GMPerformance .028 head gaskets. which yeld a .038 qwench. For a cam i chose a Retro-Roller from Comp (EX270HR) (.495 in - .502ex)(218in - 224ex @50)(110 L/S)(1600 to 5400). For an intake i chose an Edelbrock EPS performer @ 600cfm #1405 carb. This combo is right at 9.0:1 c/r, and makes close to 1hp per cubic in. If you cant affored a roller, then you can go with a EX262 or a EX268 flat tappet instead.
