HELP! Need 318 Head Suggestion (info provided)

Keep your heads. Saving the rest of the 1600 plus dollars on the edelbrocks can be spent on having 1.88 and 1.60 valves installed. That is all the valve your engine will ever need. You should also have enough to get some pocket porting work done. Also, I would do whatever I could to get compression up to 9.5. That is a safe compression ratio for pump gas and you will really see a difference in power. I mean a BLUEPRINTED 9.5, not throwin this part and that part to "get there", but an honest measured 9.5. with your cam choice and some good flowing headers with good induction, you should bump 400 HP.
