looking for the right intake for my 426 stroker

I've never heard that push down comment before
done oil through the pushaods and the shafts lots of times
most rockers just squirt oil at the adjuster (if you're lucky and the stream misses cuz the adjuster is too far in or out...)
wheras the pushrod is delivering pressurized oil dirctly to the cup
I wonder if the pushrod tip type makes a difference.
when we were doing road racing we used ford sized adjusters and 3/8 pushrods and offset rockers
