Cylinder head decision for 318

You either take a small chambered head for compression and port it to get the flow you need or you buy a small chambered aluminum head to get there. I get a charge out of the guys with a stock short block, pistons .060 in the hole and put a set of large open chamber 360 heads (for the flow) and throw in a big duration cam. The static compression is in the high 7's at best. Not the best combination
