Hey guys, just found out from my machine shop that a motor I'm rebuilding has cracked heads. I'm looing for a nice pair of 990 Rectangular port heads for a Mark IV engine that will be stroked to 496 CID. Just need the bare castings, but a complete set will be fine.

Thanks a LOT guys, Nick

Personelly I would fly with a set of Dart iron eagles. Look in the swap forum for this.

Thanks Dan. If it was my motor I would go with the Darts also, but its not. I'm rebuilding this motor for my friend and he won't spend the money... but I totally agree.

Thanks, Nick

That sounds perfect. Would be interested in the heads/intakes/carbs.
Let me know what you find out from your engine builder in terms of the heads.
