I am about to adjust the valves on my truck.
I cannot find the specs to adjust them to, and do not have a manual. can someone help me find the specs or where to find a free manual?
Also, not exactly sure how to measure, as i have not domne it before.
Is this right... Measure w/ feeler guage between the valve and rocker arm that contacts/opens it while its closed...? Also, how do i differenciate between intake/ exhaust valves?

 

Stem-to-guide clearance ranges:
0.001" to 0.003" Intake
0.001" to 0.004"Exhaust

 

Like i said, i have never done this before lol.
So if you dont mind filling me in, what exactly is stem-to-guide? How do i measure it? Thanks
