RMS heads???

I think ya mean RHS?

Brain does some touch up wrk and lite porting (IIRC) and the flow very good. For a brand new casting, there an excellent replacement head with good flow potentail to make some really nice street power. Brain said he was able to knock down a 10 sec. et. at the track. On a stroker, 400+ cube engine.

How well or ast it'll go on a standard stroke engine IDK, but it should be able to put a smile on your face.
