I am rebuilding my 454. I just got the heads back from the machine shop where I had the seats ground. I have brand new valves for it. Springs will remain stock. Cam is only a step up from stock (Edelbrock 2162 with matched intake manifold).
My question is - is it worth lapping the valves? I have searched here in the forums and cant seem to find a definitive answer concerning new valves.
I know how to lap them having done it a few times over the years, just wondering if its even necessary given the valves are new and the machine shop done by a man I trust completely.
