They gave me some Fel-pros that looked pretty good, but I have noticed that the middle ports on the gasket are together, Insted of the middle being seperated on the gasket like the old ones I took off. Does this matter? I went ahead and installed them, they fit perfect, just wondering about the middle port holes being sealed only on the outside, not seperated by a ridge of gasket?
