Quote: are you running the regular felpros or the performance ones I am running the felpro performance part # 1008 on a 416 with 12.8-1 timimng locked at 37 degrees and have had 0 problems so far.
I believe they are 1008's but I'm not sure. I am really bad at taking notes. The number on the gasket itself is 8553PT with a R12 under it.
