Intake manifold install question

[tnplumber]

My intake manifold is leaking on my stock 318 2v.  I have never changed the intake valley gasket on a sb mopar engine.  Are there any pit falls I should look out for?  Looks pretty straight forward.  What type of sealant do you recommend?  What about the carb linkage? I am guessing I should just leave the cables installed and just unbolt the bracket?  Also the car car has functioning A/C.   

thanks in advance

no valley gasket on a SB ... pull it, clean everything up then use a little rtv on the corners and put it back together.  easy as pie ...

When I built 318s and 350 chevys in a marine engine shop, we always threw away the end rail gaskets and used a bead of silicone on the rails between the two sides.  Seals way better.   Use Ultra Blue, let it set up for ten minutes, then install the intake.  After it dries, you can trim it neat with a razor blade.
Do not use the gaskets and silicone together. The gaskets will ooze out as you tighten the manifold. If you are going to use the rail gaskets, just do the corners like 68val sedan said.

   You sure it's not a '72?  Now I'm sounding like the idiots at car shows who know more about your car than you do.

The best stuff for the end rails, is "The Right Stuff". Thats the name of it, not being a smart *ss. Its black, so you don;t get that contrast. The stuff is almost as tough as a tire when its dried. That stiff will not leak.

Dont forget to drain the radiator since SBs have coolant running through the intake.

Nice ride. Is it a driver?

  Sometimes the dirt accumulates along the intake and head mating surfaces. Either 75c car wash it first or tooth brush and shop air it off so no nasties get inside. Also a good shop vac is helpful for getting teh gasket shavings out of the ports. Just don't get caught using the one for the house,  if you know what I mean.

Dude, I always vacuum with the shopvac. It works mint.
