My neighbor asked me to help with a Massey 33. Here is the story. It sat for 10 years and he decided to get it running again. The engine was stuck and they bent push rods trying to free it up. Also found 2 valves froze. They replaced the push rods and sent the head to a machine shop to be reconditioned. They replaced 2 valve guides and 1 valve. They have everything assembled and here is the problem. We cant get the clearances on the intake and exhaust valves. All but 1 valve are too tight. The adjusters are bottomed out. They only thing I can think of is when the machine shop cut the valve seats they took out enough metal so now we have lost our clearances. Any suggestions on how to get the clearances? We can shim the rocker arm but I don't really like that. There are little caps on top of each valve. Should we file/machine these to get our clearances?
