I built a 327 with flat tops and 416 305 heads. I put 1.94 intake valves in and ported the heads out. The problem comes with the cam I picked out and the compression of the engine.
I did all the compression calculators and 9.6 to 1 is what I came up with. I plan on running 91-93 octane in the truck. here is the cam I put in the engine
