Fel Pro 1406 is a header gasket, not an intake manifold gasket. I went with good ole fashion GM LT4 intake manifold gasket. Part number is in the pic. You will need to buy 2. They are sold individually.

Are you sure there is just one in there? I just came from the dealer and the parts guy assured me that if it's a kit, that two are in there. I had to order it, so I ordered one kit. It ran me almost $30.
I had him look up the gasket # for an LT4 GS Vette and that intake gasket # is different than the one in the pic. They are both kits. Now I am all confused.

You have to be careful also. There are two LT4 intake manifold gasket kits. They are both GM. One is for fuel injection and one is for Carbureted LT4 manifold. I think I ordered the wrong one. The 12367777 number was a good GM number but the parts guy could not trace it back.

Just verified with Pace Parts that the number for fuel injected LT4 is 12528884 It comes with 2 per package. This is also the same number that comes on the LT4 Vette. The other gasket is for the carbureted LT4 that they sell as crate motors.

Ok, my bad.
Just pulled the intake off tonight and I did have 12367777's on there. I bought the 12528884 and they will work too. They have more meat around the outer edge and are not good for heads that are ported on the intake side. If you ported the intake side, you want to go with 12367777.
