Am I missing something?
Finished putting the engine back in my 72 gto and bolted the intake down with Felpro gaskets. I noticed this uncovered crossover hole in the head after I bolted it all together (see pic). Is there a special gasket that is supposed to cover this hole? Won't the exhaust come blowing out? Is there a block off plate that goes there?
Thanks in advance for any help. |

That stays open.as long as you used 72 gaskets, they go below opening. 72 and newer.
Those are 72 or newer heads and intake, right? Sent from my Moto Z3 Play using Tapatalk

So why is that open? Won't the exhaust come blowing out, or is is just for heat?

That is a separate hole not connected to exhaust on 72-newer.

And yes, those are the original 7K3 heads and original manifold.

If I remember right, that hole is a non functioning closed off hole. It does nothing. I worried about that when I put mine together too.

What I found to explain the blind hole was that the purpose of this hole is to relieve heat from the cylinder head’s exhaust crossover passage.
Mopar 318CI - "The hole in question is to keep heat from the ex-crossover away from the oil under the valve cover which would quickly carbon-up if the air gap were not there." Ford also did this. Photo is of a Mopar head/intake showing the blind hole/gap. |
