Got the manifolds resurfaced for 60.00 and after some very mild port matching, I installed them with Mr. Gasket 5936 header gaskets. Do to core shift in the original manifold castings it still leaked on the pass side where the gasket didn't quite cover the edge of the manifold. So refering to the fact they came from the factory with no gaskets, I removed the pass side gasket, cleaned both surfaces and reinstalled. Suprise! NO LEAKS! So the lesson learned and to pass on is: Resurface your old manifolds before installing and don't waste your money on gaskets.
