Fel Pro 1312-2 Cathedral Port Intake Gasket (Pair)
Fel Pro print-o-seal gasket for LS Square Port intake manifolds/cylinder heads. This gasket is for square port cylinder heads. This item is one pair of gaskets. One package does one engine
We find these gaskets work very well, and ease troubles sometimes caused by using the O-ring style intake manifold gaskets, particularly with engines that have milled cylinder heads.
Best of all, they're really durable, so you'll get several installations and removal from a set. Keep a set for the race trailer handy, just in case!
