refer to any automotive repair manual such as Chilton',s Motor's, or Haynes for complete step by step instructions...

Well, yeah. But if he had the manual he (or she) wouldn't be listing this question.
Depends what you are doing, but of course you might as well check all valve clearances since you have the valve cover off. Remove valve cover, move crank manually so that the cylinder you're adjusting the valves on are at TDC (top dead center) or the push rod is at it full down position (making the valve top and rocker at it's loosest position). Check specs but I think it should be .015 clearance. You'll need a feeler tool for this. For each cylinder you move the crank, maybe a 1/4-1/2 turn to get TDC then check each cylinder in it's firing order 18436572, but double check per specs that apply to your vehicle of course.
The intake valves are in the intake ports, the exhaust valves are in the exhaust ports.
how adjust the valves
Sorry I messed you up
1 exhaust and intake. Each pair of valves should be adjusted when the cylinder is at the TDC of it's compression stroke.With #1 at TDC you can adjust 1,2,5,7 intake and 1,3,4,8 exhaust.
You can adjust tapping valves by adjusting the lifters.
Yes the intake and exhaust valves have to be close.
Trace the runners. You can see the exhaust runners leading to the exhaust valves, and the intake runners leading to the intake valves.
0.016" both intake and exhaust valves. Make sure its cold and when adjusting the valve you are adjusting needs to be closed all the way.
Exhaust valves are always smaller.
The intake valves are bigger, and lead to the carburetor. the exhaust valves are smaller and lead to the manifolds or headers.
The intake valves line up with the intake runners on the intake manifold. The exhaust valves line up with the exhaust runners on the exhaust manifold or headers. With #1 at tdc you can set 1,2,5,7 intake and 1,3,4,8 exhaust valves. Rotate the engine one revolution to #6 tdc and set the remaining valves.
look at the head with the valve cover off find where the exhaust manifold goes in tha is the exhaust valve or looking at the valves the first one is exhaust then intake then intake ,exhaust,exhaust,intake,intake,exhaust if you have the head off i think the intake valves are bigger than the exhaust
