These are probably not the gaskets you are looking for if they fit the 302 with a standard bore size of 4.00. The number you need is 3995633 which is for the 283/327. I would ask the seller for a part # before you bid.

Those are probably 711 gaskets

Dear Moron, I happen to have 8 new 3995633 gaskets still in the GM package. Give me a call at 419-706-5055 if you need them.

Just noticed a mistake in my earlier post. Should read 283/307 Not 283/327.

With these #633 gaskets gone, is there a low-cost alternative for the small-bore engines ANYWHERE?? .018 thickness is o.k....but .020, or .022 would do too.....

ss wannabee · 02-24-2010, 11:42 AM

Not sure on that bore size.....anything smaller?

Get a hold of Brad Zaskowski. I think Bill said he had some of those from earlier years of running the 283 in SS
