Valve lash

Checking the adjustment on my valves in the 340. It has a Hughes #HEH2328AL hydraulic cam with crane gold rockers.

On the cam card it reads .000" Valve lash Hot

On the Hughes website under the install directions it reads: "Hydraulic lifters should have approximately .040” to .080” lifter
pre-load, (1 to 2 turns on the rocker arm adjusting screw)."

Heres the link. http://www.hughesengines.com/Upload/productInstructions/New_Camshaft_InstructionsMar2010.pdf

Not sure how to set this correctly.
