340 Exhaust Question

Hey Guy's, I have a 71 340 that has the J-heads I ordered the wrong exhaust gaskets for the headers (Big Block) and was in a pinch and had to run to Parts America. 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?

Am I OKAY

No biggie on the open center. Run it.

If your running stock heads the two middle exhaust ports are connected anyway so there is no performance penalty provide they don't leak.
