I have them on my 390 stroker and they are good quality castings and make decent power... These heads will make more power than any non W2 iron stock small block casting...

I got to disagree though about the best non W2 iron head. I like the RHS and R/T better however they are both discontinued and were not huge improvements over the EQ, just a little better.

Use a Comp rocker or Jesel rocker arm if the budget allows. Stay away from FBO as a source. Queat Ind. is an international smelter and produces high quality auto parts.

If CME can supply different valve combos any chance that they would fit hollow exhaust valves with sodium filling?

It looks like shrouding is definately an issue to a point but I think it still flows better than the 1.92 intake as some flow bench results show..... overall, I like these heads and feel that for a not to racy street/strip combo these heads are hard to beat.

Price wise, does the conversion come out the same as using the Edelbrock LA type heads? The Eddies cost more but I can reuse my pushrods and rocker arms/shafts. The Magnums Id buy from Clearwater are $900/pair but Id have to puy the pushrods, lifters and rocker arms to complete the conversion. Both heads I believe would require new head bolts?? Do I save any money with the heads from Clearwater when all is said and done? Keep old mopars alive.

The cam I already have is .514" so additional springs will add more $$$ to the conversion cost. Keep old mopars alive.
