Will these gaskets work with my '00 3400 heads &intakes?

[Syn]

will the lim gaskets from a 95-99 3100 work for my 3400 ? i didn't know if they were diff sizes

I'm not sure if this helps but the 3100 headgaskets I got for my 3400 topend on 3100 swap (12590863) have 92mm diameter holes for the cylinders. Last I checked 3100's had 89mm bores and 3400's had 92mm ones.

i am talking lower intake manifold gaskets, i am thinking they will i am told they will and i am told they won't need a for sure answer. i had some old ones laying around and they looked like they'd fit but i can't find em no more

no, IIRC the 95-99 3100's had a different intake manifold then the newer 3100's.

but I'm know to be wrong from time to time

No, they are different.

yeah different, i cut the dowel pins off and used the gaskets anyway. i found a set of intake gaskets for a 3400 on ebay and used them on my 97 3100. 22,000 miles and they are just fine!
