318 low oil pressure

I'm back, sorry for the long delay on a update, today we took the valve covers off to do the gaakets. Inside all the passages were clear and the valve springs and rocker arms were like new. The oil pressure has been good from when we changed it from 10 30 to 10 40. Below are pictures I took of both sides of the top of the heads and one of the bottom of the cover itself with the new gasket.
Thank you guys again for all your help and imput
