Went up to Summit in Reno to pick up the #1487 Fel Pro gasket. Talking to them, it is very common to NOT run a gasket as many of you state. No one around here sold that particular gasket.

As Panavia states he uses the #1415's on small port headers and #1487 on the newer 402's. I matched the 1487's to an AFR 205cc head at Summit. I also matched the 1415 gasket to the small 185cc heads. The 1415's seem to be the gasket for stock size 351 ports and 185cc heads (not on Roush 427's).

One area of concern is between the port and the bolt hole. As shown in the photo, there is only about 1/8th inch of gasket space and part of it protrudes into the port to be burned off.

I'm ready with the gaskets but just want confirmation there's enough gasket coverage to seal and not blow out through the bolt hole .

Check out the photos of the two different size Superformance headers and my headers, ready to clean and install.... Is the gasket safe or not? Please......
