So I am finally getting around to putting the intake back on the Olds.

I bought the turkey tray gasket and some rtv. The guy at the parts store told me to put rtv on around the water ports and a thin layer around the intake ports. He also said to once you get the gasket in place to wait until the rtv sets before putting the manifold intake one - to be safe you could wait 24hrs.

His comment about waiting up to 24hrs before putting the intake back on seemed strange to me. What do you guys think?

I've got a friend that likes to "stick the gaskets". He bonds the gasket onto the engine with silicone or some gasket sealer then waits a day. I can honestly say I've never done that it the 35+ years of working on cars. It probably isn't a bad idea but it seems like a waste of time to me.
We just installed a tri carb on a 455 and put a very LIGHT coat of silicone on the turkey tray and a little extra in the corners.We used the factory rubber ends and never had a problem. I like to throw away the rubber ends and fill the ends with silicone now days on my own cars.

 

That does sound strange to me for sure.
I have never used the silicone sealers so i am not sure if that is valid or not.

Here is some good advice about the intake gasket:

First, the surfaces must be perfectly clean.

2-3 wipes with laquer thinner on a lint free cloth will remove the oil, grease, or anti freeze.

This is how I do mine:

1. Apply a thin bead of The Right Stuff gasket maker around the water ports

2. Apply a thin coat of Brush Tack around the intake ports

3. I discard the rubber end seals, and apply a thick bead on the end rails

CAREFULLY lower the intake on, and be sure not to dislodge the intake gasket.

Then, using the factory torque sequence, tighten the intake bolts.

I wait 24 hours before starting.

And, if you have a coolant leak tester, it may not hurt to pressurize the cooling system to be sure there are no leaks.

 

that's pretty much dead on!

you've done this before

 

Well I have the intake on and almost everything hooked up. The test will be once I fill it and do a pressure test. Thanks for all of the advice.

I've put the intake manifold gasket on the intake with RTV and installed it the next day. I've never done this with the turkey tray though. I didn't use the turkey tray when I reassembled my engine.
