Is this going to be a problem?

Well, I was getting ready to paint the block on my 454. As I was taping up the heads around the intake, I noticed the cross over heat riser ports are exposed on the heads...The intake doesn't cover them.

Is this a problem? Are these under pressure? I believe they are tied into the exhaust ports somehow. I think my intake gaskets will cover these up...

See these pics...with intake in place:

I beleive this is the correct intake for the motor. Its a Edelbrock Performer 2.0 dual plane. The motor is 454 out of '84 c3o wrecker.

no the intake will work .the port is to the in side of the open part of the head casting the cavity that you see is not the port ,what you need to worry about to cover is about 1 1/4 by 1 the casting cavity around the port is to keep oil off is port the gasket will cover the port part of the heads is has nothing to do with how it will run

wheewww..thats a load off my mind. thx Pat

all stock big block heads look like that from 65 up to the late 80s

This my first big block..
I'll be checking that out on other peoples engines at car shows this summer.
I never noticed it before
