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. It was recomend I use the PRW 1.6 roller rockers, which I bought. Well for the life of me I cant get the damn things set up right. If I shim the rockers to wear the roller wheel is centered on the valve, the damn push rods rub the heads at max lift, so then if I get the push rods centered in the cut out in the head, it puts the roller real close the the edge of the valve stim. But even getting the push rods centered in the cut out of the heads. At max lift the push rods are touching the heads at max lift. Trickflow says the heads are cut for 3/8 push rods. But I am not seeing how. Looks to me like the push rod holes in the heads need cut deeper and wider. But in you cut much more you will either be cutting into the valve cover rail or possible into the intake runner.
Very sorry for the long winded post, I am just vinting..i am not smart like all you guys on here and maybe this stuff is over my head. So I am looking for advice on what to do? I mean go down to a 5/16 push rod or bite the bullet and get the $$$ harland sharp rocker arm kit
