Can these valves be lapped and put into the factory valve seats or do I have to have the valve seats replaced?

Answer QuestionPsychic valves are designed to be treated just like the OEM valves you're replacing. The can be lapped to work with the OEM valve seats on your machine. Of course, you'll want to be sure the seats themselves are in serviceable condition, but assuming they are - then you shouldn't have any problem fitting these valves to any machine you select from our fit guide.
