Head Help

Rumblefish thanks for the numbers. You and GTXperience are right about everything needing to work together. So I guess I should ask this. I was going to reuse everything I can to keep the cost down which would include the stock rotating assembly, the mopar single plane intake, the heads, a comp cam 294/306 duration 519 524 lift cam, 1.6 roller rockers, modified 770 holley double pumper and 1 5/8 headers. Anything stand out as wrong? How much if any port work would/should be done on the heads to have them flow well enough? It'll be a street/strip motor and I will be putting it on the bottle at some point.
