Anyone know the part numbers for the LT4 intake gasket set?
Felpro(if there is one) and GM.

Thanks

 

The GM part # should be 12367777

 

Is the GM version better than the felpro version(if there is one). The GM ones are $13 a piece!

 

Does felpro even make LT4 gaskets?

 

AFAIK, the only intake gasket is GM's, which works fine. PN 12367777 is what you want. For some reason, the original production gasket covered part of the intake port and these do not. You need to order two, as the PN is for just one gasket. Not sure why they market one, it's pretty hard to remove the intake from just one head

Ok thanks Rich, I wasnt sure why they will only sell one too? Oh well.
