i have a 77 RoadRunner drag car. 2700 lbs race ready. i would like to run low 10's with a stock stroke 360. ladder bar suspension, 4000 convertor, 4.86 gears, 727, 29.5/11.5 slicks

i need to buy a cam, (solid flat tappet) and heads. i'm thinking about the 220 CNC BPE heads. or can i get away with the 205 CNC BPE heads?

with the X heads that i had on, the compression was 11.8 at 74cc. BPE heads are at 70cc.

question is this, what solid flat tappet cam? big or small BPE heads?
