So now I'm at the point of installing my Edelbrock air-gap intake onto my AFR heads. I have a set of Felpro blue gaskets and the robber end seals that go with it. I was following my engine build book and got the intake on with the bolts just snug. When looking from each end there is a fair sized gap that the rubber seals don't look like they'll seal up.

So digging through all the Edelbrock paperwork I found the installation directions specific to it . I have a few questions about them:

1. Can I use Aviation Form a Gasket on the gasket surfaces instead of the Edelbrock sealant?

2. It says to use RTV sealant on each end, I have red high temp and black RTV, would one of these work and how thick can this be to fill the gap?

3. Should I not use the rubber seals at all?

Thanks again,
Sean
