We need to distinguish between adjustable valve lash (mechanical lifter adjustment [hydraulic lifters make such systems "zero lash"]), and adjustments sometimes necessary after grinding valves and faces, milling heads and decking blocks, etc. to get the velve to static lifter dimension back into the range of accomodation of the hydraulic plunger. Though this is a common procedure on the L-head engines with hydraulic lifters, it is also occasionally required on hydraulic lifter-equipped OHV engines as well.
