The intake manifold gaskets I removed from my old 305 had restricters on the 2 rear ports. The intake gaskets that the new 305 came with have no restricters on the rear 2 ports on the gaskets. What should I do put the restricters or not?

for what kind of intake? if its an aftermarket like a performer rpm i dont think they even have a passage in the intake so either way wont really make a diffrence. just be sure you use some rtv around them so they dont leak

i would think you would be fine either way if its just stock, i think the reason or the restrictors is so the intake doesnt heat up so much.
