3100 and 3400 lower intake gasket.

[MasterJacko96]

is the lower intake gasket for the old 3100's the same as the ones for the new 3100/3400's? I' just wondering because i have a lower felpro intake gasket at home from when I changed the 3100 intake gaskets. I put it on when i changed them and 2 weeks later i had to get a new valve put in because of a lost bolt that decided to make a home inside my engine. they fixed that and gave me new head gaskets and intake gaskets gm brand which fell apart once where i had to get them redone again lol. anyways the 1st time they gave me the felpro ones back after spending 2 weeks on the motor. They look fine can i reuse them when i swap 3400 intake manifolds and hads on?

Um they have changed the design for better sealing. So I would buy the newest ones avalible.

The old ones were the leakers prior to 2000 I believe
