Are all the valve steems sopposed to have caps? or just the intake or the exhaust?

 

only the skinny ones so it should be 4 per head

 

only the exhausts, but lash caps suck and if you end up diong a valve jobe replace those suckers (hell, replace them all - even if you use used valves from later model 302/351's.... they have a better stem material and dont wear like the old ones)

 

much appreceiated

 

Plus those caps will get destroyed with any roller tip rocker.
