LA engine Magnum Heads Pushrods?

straightline im using 7.750s but thats with solids.1.6 Crane Gold rockers ball to ball with the comps #801-16 AMC,Chrysler P.S Dont use the 821-16s which have the hole in the cap only,can be used with the LA head due to oil feeding through the head bolt where with our combo it relies only through the lifter pushrod.
