We do the heads for James Antonette's SS/CS engines with those heads.Not going to be easy to make that power with flat tappet cam. He has been 9.20's with the car in that class.

Dart has recently came out with some decent stuff but, your asking alot with that combo. I don't know how good they are.

I do not think there is a program for the new Dart head yet or a piston to fit the chamber.

As I understand, the new Dart offering is based on the prior offerings from Racing Head Service (RHS) when they got rid of all their cast iron heads.

The spark plug location on the RHS is to low if you cut the head.
