Thanks john and MD ,I thought I replied earlier but I guess not.The speed shop I use installed 4 new bronze 3/8 exhaust valve guides reamed to .0035 and new valves.
When I told them I had a recommendation of .005 ,after they were already done,said he would cry if he had to do .005.
This was kind of funny because the motorcycle cylinders he has been doing for me for years have .005 as stock clearance,cast iron guideSo I will find out if .0035 is enough.
Pistons were fit to .003
