Hey yall, new to the page here. Got a 85' roller 307, with the stock 5a intake. Need to order some intake gaskets for it, and having trouble finding the correct ones. I'm seeing two different styles, one, is a simple gasket. Nothing fancy. The other has a valley pan built into the intake gasket. Wondering which would be correct for my engine. Its also got 6a heads. Thanks!

The valley pan is the factory gasket. The gasket available is probably for earlier flat tappet lifters, it may contact. The ports will also be larger on the gasket. You could use the early shim gaskets or the composite gaskets. The composite gaskets are much thicker and may not work without cutting the intake. Use RTV around both sides of the 4 corner water ports. I use a tall, narrow bead of RTV in place of the rubber end seals.

Do you have a link for the roller style intake manifold gasket?
