i'm having problems getting a good match for a seal on my head to header gaskets. my head ports are larger than my header ports. i have the normal 1 5/8 headers and when i match the gasket to my head port there is very little seal left on the header. it's real close where the bolts go and it looks like a seal problem will happen. if i match the gasket for a good seal on the header the gasket hangs over too much into the head port and looks like a big restriction. schoenield makes a 1 3/4 primary tube header and that looks like it might solve the problem. what do you guys use? thanks.
