Fel Pro 1222-2 Square Port Intake Gasket (Pair)
Fel Pro print-o-seal gasket for LS Cathedral Port intake manifolds/cylinder heads. This gasket is for cathedral 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. Stop the vacuum leaks!
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!
