Yet another first time build question

This is quite the saga for me so far.
Small block chevy 350... Valve lash specs?

 

Zero on a hydraulic lifter cam....18 and 20 [cold] is a fair place to start with a solid lifter cam until you can find the specs for the cam.. 18 on the exhaust valves and 20 on the intake...click click click click click click

 

What cam? hydraulic or solid?

 

Sorry, its a hydrolic cam with roller lifters.
