as an engine builder there is one thing that i can say,valves take a seat,and clearances do change after initial setup.you will prolly notice that in the manual it might call for a 10 hr valve check then after that it might not call for it for another 100 hrs.i would do the check,chances are no adjustment is needed but better safe than sorry.as for cover gasket...they are a rubber gasket and are reusable if taken care during disassembly.also as far as the 500 mile comment,one thing to consider is rpm and load,marine engines are under higher loads and rpm so in truth 10 hrs on a marine motor is equal to in the neigborhood of 200 in the auto world.hope this helps. jeff power unlimited marine 256 749 1584
