Intake manifold gasket?

[Harlow]

When I pulled my intake I found that it didn't actually have a gasket...it had that spread on gasket maker. Do I need to have a gasket or can I just do what the previous owner did?

Leave the intake ports dry, don't put anything, the gas & fuel vapors will just delute it & possibly leak, plus it'll suck that crap down the ports, just use some black RTV on each corner & a thin layer across the F&R rails, you should be fine & NO leaks if the intake isn't warped any

I siliconed the front and rear strips and then sprayed some copper seal on the intake port section of the valley pan.  So far I havent had a problem.
