Think I'll be ok with three threads showing on my adjusters? Isky ductile's w/.579 lift ft solid w/380# over the nose. Why does everyone reccomend only one thread exposed? Is it for structural or oiling purposes or a combination of both? My geometry looks perfect and I don't want to have to buy new pushrods....Again



The greater it sticks out the more side load you
put on the adjuster when its at lift. Plus if you
were to lay a straight edge across from the valve
tip surface thru the centerline of the shaft area
you would see that the other end would be right at
the edge of the rocker, that would be thew ideal
point for the adjuster to be. Also the higher the
rocker ratio the worse this condition will be(the
threads sticking out)
