Deep into a 1982 318 build. I have no idea how the rockers get oil. As a former Chevy man, the lifters pushed oil up the hollow push rods and ta-dah the head has oil. This 318 has solid push rods. So how the heck does the top end get oil?
The oiling system isn’t as high profile or glamorous as heads, cams, and other parts. But as we all know, it plays a vital role in the performance and longevity of an engine. The oiling system touches all of those parts. Clearance is an issue for street cars and street/strip vehicles, so you...

Number 2 and number 4 cam journals have oil holes in them which allow the oil to travel into the heads. Be sure to note the notch in the end of the rocker shafts. They need to be put back the same way for proper oiling. Little trivia here. You can use AMC oiling lifters with hollow pushrods and it'll oil like your Chevy. This is the de facto mod when putting the 90's Magnum heads on a pre-Magnum block. The Magnum heads use AMC style stud mounted rockers, and the do not have the oil passages in the heads, so they have to oil via the pushrods.
