Thought I was saving a little money. They dont fit. Rub on the intake elbows. You have to grind a little off the sides to keep from rubbing on the intake elbows and to secure a tight fit with the exhaust risers. I will not buy them again. FAA-PMA and are different size than the TCM 627429.

Great gaskets, but the fit was not good. Had to remove some of the steel carrier ring to get them to fit.

This is used as one per cylinder.

Q: Can part # 08-05270 (spiral wound exhaust flange gasket) be reused, or does it need to be discarded after each use?
