in the 5 seasons i have on my boat, ive only had to adjust the valves 2 or 3 times.
the biggest downfall is that when you leave a solid flat tappet engine sit for a while, its advisable to back the rockers off.
so you dont have premature wear in your valve springs.
once you get the engine up to temp, adjust the rockers, and tighten em down, you dont have to worry about it much.
unless its a hi po race engine, then i would be adjusting them every run lol
