i have a weiand tunnel ram that has been lightly ported , possibly gasket matched. i don't have a valley pan handy to know exactly how much but i can see it has had some porting done. gasket matching my heads is just not an option right now. ive heard the mis-match may cause a hesitation. this is basically a factory spec 8.5 to 1 , 452 headed 440 with a 484/280 cam that will never get hammered on. will it be a problem? what say you?
