Have a 1998 chevy blazer, changed intake manifold gaskets. Now oil pressure when engine is cold is 40 psi after 10 mins pressure drops to 15 psi.

5 psi per thousand rpm is acceptable oil pressure. It is hard to mess up oil pressure by changing intake runner gaskets. Oil pressure is made by bearing clearances mainly. A little higher viscosity oil, like 10w40 might improve oil pressure slightly
