Cylinder head dyno shoot out

I’ve got two sets of wild iron heads that I’d love to see the potential of, and I’m right here in NC!

One set of heads are some super ported “W1” NASCAR heads. The other set of heads are “810” W2 race heads that were fully race ported by Diamond Elkins back in the day.

Both of these heads have been ported to the same size as Indy 360- square port heads.
