I just picked up some gt40ps with about 30k miles on them. They have just been cleaned up and had new freeze plugs and exhaust valves. How can I tell if I need a valve job? I can get pics if you need them.
Do I need a valve job?

Well does anyone know the max lift on the stock GT40p springs? I believe its around .530, but I'm not sure.
