I have a closed cooling system with center rise manifolds and 3" riser extension blocks. What is the preferred gasket at the manifold to extension block connection point? I would have thought block off gasket then block off plate and block off gasket. When disassembled it was open gasket then block off plate and open gasket. It doesn't really matter as long as the plate is there right???
Thanks!

With the plate there it really make little difference .
