The factory stamped steel rocker arms that are listed by the factory as 1.5
ratio are lucky if they are 1.42 ratio, so you are giving up some cam lift.
Also if we are running a hydraulic cam in a race type vehicle, we set the
push rod  preload at about .0015 so there is less chance of lifter build up.

 If I'm not mistaken, these rockers were = roller- 1.6 ratio.  Can be
used on both solid and hydraulic cam lifters, and the adjustable part
makes them go either way. May also help with minor differences between
manufacturer's pushrod lengths, and block decks not squared.  Don D.
mentioned block decks not too long ago in one of his informative emails,
as not always correct from the factory. And it was also mentioned lately
that some cam manufacturers want the lifter adjusted so as not to pump up
at high RPMs, and stock rockers on shafts only fit one way, right, or
close enough, for factory production.    Tom in Dallas
