heads

I have a ported + polished set of X heads on mine - it made over 500hp on the dyno... Cam is [email protected] (solid roller), 13.5:1 compression, Arias pistons, etc. I had considered the Edelbrock Performer RPM cnc ported aluminum units, but I'm told I probably wouldn't see any gain using them, other than the obvious benefits of aluminum. A good choice would be a set of Indy's or Mopar Performance W-9's. Problem is that both of those heads require special exhaust, valve gear, and intake manifolds.
