I could actually slide a .010 feeler gauge betwen block and gskt,luckily i caught this while it was still on the stand. I bought another felpro 1 piece gskt and the fit was just as bad,i don't blame the gskt,i blame the pan,just curious if you ran into same problem. I ended up using cork gskt's with lots of black rtv,it doesn't leak but i wouldn't buy another hardin pan again. Patriyacht is right,are you running correct bypass valve set-up,there has been alot posted on here lately about near identical problems,good luck,Smitty
