They look like an affordable cathedral port aftermarket casting. Available bare "as-cast" in 205cc and 225cc versions w/ 62cc combustion chambers. Just seeing if anyone has any real world experience or knowledge about these? Anyone know the deck thickness? I know the more expensive Pro Elite castings have a thick deck. Any idea if they're cast overseas or here in the U.S.A.? Do they require aftermarket rockers?

If my sources are correct, they are actually a Dart head, with RHS logos...Which is made in USA

Yes they are a Dart head. I called Comp and asked who was casting them as they were one of the items on my list when purchasing new heads.

I'm not a real big fan of the Darts... Didn't they have a problem with rocker guide alignment? Not sure if that issue was ever resolved??

So these are not the ET heads that were rebadged . I thought these were either leftovers and or non CNC ported Pro Elites .

I guess not. Too bad for us, seemed too good to be true.

That's still a great deal but I figured RHS started making more castings . Who knows, maybe a CNC option will show up . I don't understand why they would have Dart cast them if they bought Pro Action Heads a while ago .
