Thanks for the info. I found a set of redone J heads for $800. If I picked these up, would I need to get them ported?



Have you looked at the EQ heads? They are based on Magnum heads, closed chamber, flow way better then X or J heads, and have a thick casting so they could be ported out. If you are on a budget those would work well out of the box and later on you could port them out. A brand new pair complete is less then those J heads:

Or with some port work just a little more then the J heads:

If I was going to go with iron heads those are what I would use.
