intake manifold gasket question

rex12348490B to Mechanic Advice@gearhead.town · 1 year ago

I’m replacing my intake manifold on my small block Chevy 350 and on all the video tutorials I have seen, They say not to use this wall type of gasket and just lay RTV on the surface on the front and back of the engine but on all their examples the sealed surface is smooth and on my engine it has these holes in it. Do I still need to use the gasket or is RTV enough?
