Edelbrock Pro Flo 4 EFI

I found some 360 J heads for about $1550 on Ebay but I'm worried that the large chamber size will significantly drop my compression ratio. I think the most logical alternative would be to by Aluminum Edelbroch RPM heads and their EFI system.

You can buy brand new edelbrock heads from Jegs for $1539, that will out perform a rebuilt J head in every way.
