If Superformance wants to send me enough to make a pan gasket..... "I'm your Huckleberry!"
I'll bet most MP steel pans leak between the middle 2 front holes, I'm thinking about just making a 1/4" thick steel bar "straddle Plate" and use longer bolts. If it has the slightest bow it's a clamping issue.
I can assist you with that request....
how hard is that material to cut ? i would feel better using the factory plastic gasket if the sealing ribs were lots bigger, but maybe just cut my own or wait until the "proto typing"[] is done.
