I'm not an engine builder or a head porter. I was just asking the question to see how much an all- out port job + shipping to and from a reputable head porter would cost vs just buying heads that will deliver the power level you want without having to spend extra money on them.

I went with W2 econo heads on mine. The bare heads weren't all that expensive, but the offset rockers and shaft setups were rather spendy.

I know Indy makes several small block heads that are likely have more potential than Edelbrocks.

Mopar Performance used to sell Commando heads. I don't know where they rank at. MP W5 heads are good, but you would be stuck with finding a used set these days.

Brodix makes Mopar smallblock heads too.

Talking to RyanJ or a few of the other guys on the race only board that deal in smallblocks for a living would be a good idea to help narrow down your choices.
