Had trouble finding gaskets for Trick Flow heads and valve covers. Both contact surfaces were level. So far they are better than the best in the FelPro range and steel reinforced cork/rubber gaskets. If you are building a large unit with a high volume oil pump, make sure the rear drain holes are large and tapered. That's where the leaks come from. I can recommend these pads.
