easy way to tell if i got a solid cam or hydraulic?

ok, here is some pictures of a lifter.

i pulled every single lifter, and all in perfect shape. light down in the block shows that the cam in in perfect condition. checked every pushrod, and all roll perfect on a peice of glass............................ now tell me if i am wrong. the lifter do not have a spot for oil to enter that i can see. so i say this is a solid lifter..?

now, with all this info, what should i set the lash at?

if you tell me 1/4 turn, then i will tell you that at 1/4 turn, the valves are open some, resulting in the engine having no compression. i know this because once i set them at 0 then 1/4 turn, i can spin the engine over with all plugs in by hand.
