I've had good results with Cometic copper gaskets.

Mr Gasket ultra with a coat of silver anti seize on both sides. I've used these over and over with no problems.

I use Remflex. They have been on my crossram sbc for 6 years without any leaks or loosening bolts

2X Remflex.FYI,be VERY careful not to bend them!Tom
