Does anybody know where I can get some?
The ports are funny shapes on the factory manifolds and gaskets. I would be nice if i could find some gasket that had concentric holes and were 1.750" or larger.
Uh, how about Felpro 95528. Do I have to do everything for you these days???
The header flanges are $171 (3/8" thickness) for a pair, from Ed.
That doesn't sound all that expensive. What would you expect to pay for 3/8" header flanges for a V6?
