They also require new valve cover gaskets with a very thin flange...

That doesn't mean you can't find them but he said RHS is pretty much done with cast iron stuff!

I just wish NHRA would research something before they paint it with their broad brush!

Engine Quest bought most of the RHS cast iron line.

They also require heavy new valves, no nail heads or wasted stems, and thick wall seats. Don't forget to sink the valves.
