I have a 1989 454 ltd, anyway just had the valves adjusted, I watched the mechanic and he explaind the process to me. So my question for you guys is
He showed me theat all but one valve where adjusted to tight, there was no lashing between the points, he said if he adjusted them (loosened them) that I would loose combustion. (i am having trouble understanting this)
I just read somewhere else that valves that are to tight lead to broke or bent valves.
Should I adjust my valves to spec or leave them be?
