School me on W2 heads.

I don't think I do Rob.... If you want I could see if the guy that bought the package from me could send a shot. He still hasn't built with them yet, though he's getting close. they were basically steel that was the same shape as the gasket and was screwed on to the end rail of the intake using counter sunk screws. Single gasket sealed up fine on the Indy. On the Ebrock we made spacers, but were thick and then we just used a thin bead of rtv to seal.
