I put 360 heads on a stock bore/stock piston 318 and the engine is in Loveland. I cut the heads .040, used a factory cast TQ intake with a 600 dp and a MP cam. Car beat late 90's vette, along with a few other things. Wasn't super fast and didn't own the street but was fun. Had 3.55 gears and a 1900 brake foot stall.
