I'm about to drop my intake back on, and I have OE gaskets from the dealer. I have some copper RTV for between the gaskets, but should I get some spray or use the tube of RTV for the gaskets? If so, where at (everywhere or just around the ports, etc.)? Is there anything wrong with me putting some RTV on the gaskets?

 

nothing wrong at all, just use a very thin coat on the gaskets, just make sure you use a good amount for the front and back rails

 

LT1's are famous for leaking oil from the back of the intake manifold. I used a thin strip of red rtv on mine.

 

Should I put a thin coat on both sides of the gaskets?

 

yes, and make sure when your putting the intake back on you do it in 1 shot straight on thats very important
