Couple of things that are ????. No angle plug? Wonder why limit it to two size(s) Intake volume and chamber?

But that's cool to see a quality piece at a resonable price!

All I can say about Dart 23 degree heads, or even RHS since they are twins, when done right they are fast!

All this talk about BBC running 4.60's and such, I have a guy with 434 SBC Dart Pro1's and a welded Dart manifold that runs 4.90's with a 1800lb dragster, no PA..

Heads are cast with A356-T6 instead of C355-T61.

Here I stole this off the Dartboard...............:)

They are very much like the Pro1 heads, but with a few small design differences that allow us to be a little more efficient about the machining, and most importantly, they use A355-T6 aluminum, where our Pro1 heads use C355-T61.

Bah........settle down. Get out your grinder and fix it!!! Doesn't matter where you buy the head, they never fit.
