? how to set hydraulic lifters
 

I am setting the valves on my 305 which had hydruailic lifters and roller tip rockers.I'm unsure of the "correct" method but what i did is go down the firing order, getting each cylinder at top dead center.I tightened the rockers down just so the roller tips could move across the valve tip.From what I understand, they should be set at 0 valve lash.Can anyone please explain the correct method to adjusting these types of valves? thanks, ron cubic

The best way I have found to set hydrualic lifters is to open the exhaust slightly then begin to tighten the intake rocker until you can barely turn the pushrod with your fingers @ this point the lifter is at zero lash then you can tighten the rocker a quarter turn to put the recomended .004 lash needed. simply reverse this to adjust the exhaust valves.

Would I just watch for the spring to start depressing and about how much? First time I attempted this method, I was at TDC and did the pushrod spin like you describe but I found out some of the pushrods hung up a bit and gave me a reading by feel that I wasn't confident in.thanks
