Any ideas as to what might caused excesive wear- new guide, new lifter, new valve. .004 to .005 clerance and less then 10 houres on a 48 356. Guide wear to the point of zero compression on #1, all others 90 to 100 lbs. It is the exhaust guide. Head of valve will move 3/16 inch side to side-sure beats me!
