360 oiling sytem help?

if you have shaft rockers on the 91 360 which it should be ...the oiling is the same as the 80 block..the magnums started around 92...and they do not have shaft rockers...

easy way..count the number of valve cover bolts ...magnums had 10 bolts..the LA 360 (71 to 91) only had 5 bolts.
