IIRC if you are putting 3500 heads on a 3400 block, you use 3400 head gaskets..

one problem... the 3400 gasket doesnt clear one of the combustion chambers in the head. i think i got a head with a werid cast or something.

no1 seems to have a problem with the 3400 gasket but me lol

I mentioned this subject a long time ago, but their are two castings for the 3500 heads and I believe their was a first design that was changed shortly afterwards. I could see a difference in my 04 3500 heads compared to the pictures of the one's posted in the old 3500 thread where in the eyebrow like ridge around the intake valve perimeter was not present on my cylinder heads. I was also asked about which casting number I was looking for when I called and inquired about a set from a salvager some time ago.

hmm i didnt know that, i just got a whole 3500 engine for the topend, it was cheaper that way. it was from an 04 malibu

i just looked them up on gmpartsdirect.com iirc they were a little over $100 for 2

that was for a 2004 malibu 3500.

I used and 04 malibu 3500 for the top end too...

Here are my pics from lining up a 3400 gasket on a 3500 head.

a little over 100 sounds too expencive too but a lot better than 200!!

and modified, i never thought of using the guide pins! im gonna try that and double check it b4 i spend more money

thanks guys

Yeah I would try and try again to see if you can't get the 3400 to work.

Can you trim/cut a headgasket? Hmm.

[3400-95-Modified]

not if its the fire ring over hanging into the chamber... then you end up with a pre blown headgasket before you even start it.

Ok, so the stuff is sealed and that would cause it to split apart then I suppose. Never saw one up close enough to see how they were made. I figured you wouldn't be able to.
