yes not recommended unless your interested in adjusting/replacing your valves every 12 hours of run time. This is one of the reason honda removed this valves option in the trx head- longevity. Honda tried many different valve lift cam profiles, but still had trouble keeping the valves from slapping the seats and cupping the valve.

good luck if you decide to go this direction.
