Need a bit of guidance

hmm it seems i have overlooked some details. this is my first engine build. pulled this 360 from a 99 ram.
had it hot tanked and bored .030 over.
the keith black are flat tops with fly cuts.
got a set of eq heads with the 2.02 sized valves
currently have a set of oem rockers.
the lifters are from a different junkyard 360 and one brand new one (chipped a lifter on removal)

it seems as though some of them have preload going on and some dont.

the pushrods i have are .036 longer than stock. im going to use a measuring pushrod to just double check next time i get a chance to get in the garage

also, cam is a custom grind with around .550-.560 lift and .282/.282 duration.

im a bit slow on the uptake this being my first build and all. ive never set valve lash before. im watching some youtube stuff right now.
