C2 Best Gasket Set for 390 HP - 1967?

[Tom D.]

Hello: I'm looking for information on new engine gaskets that will look as (or close to) original for a 1967 390 HP 427.

Know any potential "sticking points" that might come up in judgine?

Thanks!

Biggest problem is none of the available sets I'm aware of save GM sets produced in the early 80's have the correct "GM" logo molded into the end gaskets. I have not closely examined the reproductions for the conformance to the original shape where the manifold meets the head.

Tom, As Clupper suggestd you need to find an original set of intake to head gaskets. They are closely scrutinized at the shows. Judges look for the tabs sticking out that have the GM logo on them. They also looks at the "cut" of the gaskets in the usual spots. I assume that the 67's have the GM logo like the earlier models. None of the repros have this feature. Some of the original rubber seals have GM in very small letters and some have the GM in larger letters. Don't know which is correct though. John

GM dealer would'a sold you this set in Oct '67

Upper set (heads, intake, valve covers) # 3917955. This included intake gaskets for both round and square port engines.

I'm not saying this is what was Tonawanda installed, but probably dang close.

Check the close-up of the GM logo on the tab of the rubber end strip gaskets.
