I have a 5.9 magnum that I installed the new trickflow heads on. I am running a comp cams soild lifter. I have to use push rod oiling so I have AMC lifters and Smith Brothers push rods. Which are 3/8 x.083 wall thickness. As far as I can tell there is only a few rocker arm choices that allow oil through push rods
Comp only in 1.5/ PRW 1.5/1.6 and the new Harland sharp rockers 1.5/1.6. The instructions say to use the Harland sharp ones. But Frack man they are $922 a set on summit's website....
Small block Trickflow heads and PRW rocker arms ???
