283 head gasket

[FED 387]

I'm sorry was
thinking what we used but yes the block was overbored---comp387

FYI - I just ordered a set of Cometic gaskets. They'll make them any bore and the minimum thickness is .027".

[FED 387]

flat out will make them too--Comp387

We use Cometics on our 283s (stockers). I reuse them in teardown multiple times. We used to run the shims, but they are hard to find. Tried Coppers and they were a pain. The Cometics are nice.

Cometic tells me 100.00 each.
Chevy gasket 12.00 each.

Well for whatever its worth Flatout is/was started and staffed by several of the Fel-Pro employees when Fel Pro scaled back their hi perf division which was about the time they went into bankruptcy and pretty much left the racing arena---Give em a call cant hurt---They won't BS you that's for sure---If they know the answer to your ??? they will give you the honest truth--- Cometic has a very good product to not bashing them at all---Comp 387

Dennis 3995633 is the correct number they are .017 thick you may have to stack them depending on the deck

[ss wannabee]

The .017 number mentioned is the compressed thickness, right? What is the "squished" number when you stack 2 gaskets? I've heard that it's not necessarily .034, or did I hear wrong?

I have had this same part number gasket measure up to .019 Be very careful and double check your deck before calling it good. They are not consistant on thickness. Robin Brown also has seen this same type of variance....
