Intake Manifold Gasket ?

I recently purchased a Edelbrock 3776 Intake Manifold to install on my 318. I went to the local performance shop and was told to buy the Edelbrock gasket and use RVT sealant, not to use the FelPro Gasket because it tends to break apart. My friend who has a 73 Satellite with a 318 installed a 2176 and a edelbrock 1805 on his and claims that the Edelbrock gasket did not work and he had to buy the FelPro Gasket, but his car is now experiencing hesitation when he tries to accelerate. Any thoughts and which one is the one I should go with? I am also installing a 1405 carb with this.

Thoughts on your buddy's hesitation.....Vacuum leak somewhere around the intake, or improper instalation.
Like I mentioned, know how to do it before you start. Otherwise you will be doing it again.
