I recently replaced a cracked head with a rebuilt one. The engine runs great until full operating temperature is reached. At that point it has a slight miss at rpms below about 1800. I realize this could be several things, but what should I look for and in what order?

Hi there,

the first think i would do is a leak down test on the engine cold you may have a faulty valve seat that is leaking cold and sealing when warm.
