Is the Felpro 1233 a whole engine rebuild kit or just the intake gaskets? I have a complete rebuild set, and need only to seal the hole. My attempt to seal the hole in the passenger head failed. I think maybe the high temp epoxy was old and it never became a solid.

Find a 72 intake, problem solved.

I did it:



Worked fine, no problems at all. It's just the intake gaskets, what you see in the picture (plus the rubber o-ring).

That gasket looks like it would work great for the mis-match.

Just the intake gasket and rubber donut:

Works perfectly. The 1233 intake gasket kit comes with multiple blockoff plates, depending on what you want to block. Crossover and the hole over it, or crossover only.

Thanks guys. I think that is the way I'll go.,

Just a note, if you attempt to use the block off option with that gasket set, those felpro blockoff inserts will burn through pretty quickly. They did for me anyways, every time i tried'em.

I want to maintain my exhaust crossover, just close the upper hole in the 6X head.

Used the 1233 gasket kit on 2 cars; 69 Bird with 400 and my 72 GTO with 455. Had 3300miles on the Bird before I sold it, over 5000miles and 4 years on the GTO.

No issues at all with the blockoff plates. Still look brand new except surface soot and carbon deposits.

I never cut a blockoff plate to check, but it seems there is an aluminum sheet between the gasket layers.

There is a blockoff plate just for that in the kit

Thanks everyone. I just ordered from Summit

If you want to block it off use the 1233 gaskets and get a pair of stainless steel block off plates from Kauffman Racing Equipment or Tin Indian Performance for $13.00 a pair. These plates fit the 1233 gaskets perfect...

Or i understand a piece off a kitchen spatula works well. But it can cause marital issues if you get caught!
