    I have some ported Stage VI heads I want to try out. The spacer has a thin recess cut into it, for a valley pan. Then you use paper gaskets on top where the intake manifold meets the spacer. So is there a special valley pan that will work on there? Or do I just cut the intake port portion off a stock valley pan?

    Hughes used to sell one, but it could use a stiffener welded down the center.

      I just used a piece of sheet metal(aluminum) cut/trimmed to size, and just had the sides bent up a bit to conform to the heads.

      If you don’t drill and tap a few extra holes to physically “mount” the spacers to the heads(socket head screws in recessed holes), then technically you’d want to run gaskets on either side of the spacer.

      On my 470 stroker it is a sheet of aluminum that bolts down with the front and rear rail bolts. I seal it with rtv or the right stuff depending which I have on hand. I’ll see if I got a pic. Kim

      I have already drilled, and countersunk the spacers and tapped the heads. Bolted spacers to the heads with allen head screws. I guess I will need a thin film of silicone between the 2? There are locator pins on the spacers for proper alignment. Then I can just trim the port area off a stock gasket, and put that on before the spacer. Then use paper gaskets at manifold to head. Here's a few pics of the head showing the gap for the valley pan, and the bolts.
