Well ain't that just dandy, I was looking for a set of heads a little while back. Before my engine decided to grenade.
I'd wait for someone reputable to publish accurate flow numbers from those heads before I spent $1100 on a set. Don't even come with rocker studs.
On the other hand they would probably work very well on one of those HT383 shortblocks. I wonder they'll put the two together as a package.
