Proper Sealing of Intake to Block

Last one I put together, I used this

That's all I use anymore, it's great stuff....no wait, not great, right.

I was tempted to say it was great stuff, but....

It seems to me the possible issue with the intake to block seal is that with all the machining done to various surfaces, that gap can be too wide or too narrow for the cork gasket.  Too wide and it doesn't seal well.  Too narrow and it squeezes out.

Hi Frank! Do you think it may be best to set the intake on to see what kind of gap may exist between the two before bolting them permanently together?  that my determine whether or not to use the gasket or not? I'm still having mixed emotions of using the cork gasket or not.

My two cents worth....used the cork many times with a few leaks now and then. As the gasket sets got cheaper, I noticed more problems. Started using the RTV and have never had a leak. Nobody here has the 100% true way of doing it with out ever having a problem. One must just take a chance.......

Toss the cork.  It's a guaranteed leak with an Edelbrock intake.

I've run some of my edelbrock intakes with the cork, and I've never had a leak from the intake.  I guess a lot of it depends on how you install the cork, and a whole lotta luck!!
