    you will need to at least lap the valves in but thats a cheesy way to do it. you really should cut a fresh valve job on the seats so everything seals properly.

    Go with the Ferrea's. Cheaper and lighter than stock, you'll be a step ahead if you want to run higher RPM in the future. Any new valve SHOULD include having the seats cut in the head, stock or aftermarket.

    If you lapped them and they didn't seal well you're out a head gasket and bolts to pull the head and do the job right. Do it while the head is off to replace the valves and never worry about it again.

    Just have a good 3 angle valve job done. These are drop in replacement valves and are much better, and cheaper than the OEM valves.
