Not a matter of ??s - more a matter of "is it required" ? I have both schools of thought searching the forums. At first I figured just put the new valves in - after all, new valves, fresh seats but then after searching, Im wondering if I should lap the valves. Many have commented its a waste of time only adding wear to the valves ("like pouring sand down the carb") and other have commented "its a must". Just looking for a push one way or another (altho Im leaning toward doing it - what can it hurt)
To lap valves or not? this is the question...
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.
Opinions?
Thanks:hurray:
