You might want to check the way the valves were set. Where they set by the firing order or did he set the intakes when the exhaust opened and the exhaust when the intakes were closing. Sometimes when you set by the firing order the lifter is not all the way on the base of the camshaft. Some guys set 1/2 of the valves and then set the other half. This is old Chevy trick but I do not like it at all. Good luck, Keith
