Pro Comp heads & Dana exhaust ?
Has anyone used Pro Comp aluminum heads on a 454 mag EFI ? Looking for weight savings and a little performance gain. Also any opinions on Dana exhaust and will they fit 29 fever with twins looks like it would be a tight fit. Picked up 1 set used looking for 1 more. Any help would be apprecciated.

I agree with everyone, you will pay more in the long run!!! I had a set on a 496 stroker motor in a baja 24 outlaw.
Notice I said "had". Just like all said, dropped a valve seat and pulled an intake valve through a piston not to mention destroying the head casting in the process.
All this happened coming into a no wake zone returning to the ramp after a day of just hanging out. Can't imagine if all that failed while running hard!!!
Ended up with a total rebuild sporting some nice AFR's!!!
