Old School vs Magnum on 86 Dodge W100

your magnum motor have a roller cam core?
should work fine
92-93 5.2 magnum cam is best if you can score one

Q anyone run la heads stock rockers and pushrod oiling?
oil would come through the hole on the pushrod cup and fill the shaft bathtub
I've drilled the LA heads and oiled from the oil pressure tap - not hard to do
or magnum heads work fine too
on your heads just look for the casting number under the valve cover
on reman heads make a checklist seats? guides? valves / stem seals? springs?
you might see if there are any Enginquest heads available
and contact a&a midwest one of our members who does not sell junk (used car dealer level "totally rebuilt heads" )
someone post his link
also put a wanted in - some member may have some "take offs" that they want to move
