Hi, im still debating puting stainless steal valves in it. it has about 50 hr on it. So far the valves have not needed to be shimmed. THey have been dead on. I have had No problems starting it at all. Starts second kick everytime. Runs fine although the idle sumtimes is a bit speratic. If i dont put stainless valves in it what will happen. Is it certain they will shatter? When they do wont it drop into the cylinder ontop of the piston and really mess stuff up? What should i do? I was liking about getting a pair of kibblewhite valves and springs. I hear good thinks about them. Any input would be great. Thanks, Ryan Shaw
