isaac, actually the valves should be set about .002' - .003" larger than the
.010" stock setting. the valves won't burn and performance is not affected.
it's
cheaper to listen to a little valve noise than to burn valves. also make sure
the
engine is COLD. do not atempt to adjust while runnng. good luck. ted
