Which cam also? Need to know that first. I would always suggest using the manufacturers specs. If you don't have the cam card give them a call. I've seen solid cam lash specs vary as much as eight thousandths between cam brands and certain profiles.

ok it's a hydraulic set up with the 1.5 rockers the problem is.. it does have a mild cam not sure of the exact lift and duration it's in the 470 range

if it's hydraulic there is no lash. Rotate the until both the intake and exh valves are closed. I'm assuming you have adjustable rockers. Then grab the push rod with your fingers and spin it as you tighten the rocker adjuster down. Once you can't spin the push rod then give it a quarter turn. This should pre load the lifter. Complete this step on all 8 and your done.
