Need some help figuring out what valve lash to use on my engines. I have CBB talldeck, Crane 139651, Hydraulic roller lifters, Crane gold rockers. Have tried Crane homepage but I found 2 answers, 1/2-1 preload and on the camcard zero (0) lash with engine hot. As it is the first time with rollers and this cam I wonder whats the correct way to do it?

I think I would go 3/4 turn to be safe and you should be in good shape

I agree with Bobby D., once you find zero lash go 3/4 and lock down the poly lock, then torque the nut to 26-28 ft.lbs.

If you need any other help feel free to call the shop.
