The thing we will have to try and verify is the differences between the earlier and later S2 3800 head-to-LIM mating surfaces.
And it looks like your ideas were right on!

Sorry for the resurrection here.....

I know Don included information about these aluminum gaskets in his reworked Tech Info article, but I've been getting the impression that people aren't really using them when they do lower intake gaskets. These have been proven to work fine on cars with and without pin holes in the block rails, and in my opinion these should be the only thing that people use when they dig into the LIM. We know the other gaskets eventually deteriorate, while these will be durable with their all-metal construction.

Just a friendly reminder . If I'm beating a dead horse, go ahead and lock this thread up

I know that I'll be sure to mention it, if I see someone getting ready to do a LIM gasket replace. The reminder can't hurt, only help IMO.

I agree that it is a great idea to include the reminder. With the lowers I just did, I used the new GM gaskets, and told my parts supplier (where I got the uppers) about the new GM gaskets. He called his Felpro supplier thinking that they may have come up with a new one, also. As of last week, they had not.

Highlander and I walked into the dealer..didn't specify and they automatically had superceded with the aluminum.

While we have no long term test on durability etc... we need to think they have been changed for that very reason.

That'* a good point.... we have no long term experience with these gaskets. However, I cannot fathom how they would fail in the same manner as the plastic versions. As long as they don't leak, I'm confident in recommending them to other people.

Ben I agree with that.... The Plastic is not exactly designed to deal with the constant heat that they are subjected to...

The Alluminum frame will be able to tollerate the heat issues and in my eyes expand and contract with the heads and the intake... The only question will be how well the impregnated silicone beads hold up over time... But it looks like a good solution..
