So I have a 451 in a 72 Demon. Long story short the cam wiped a lobe and at least one lifter its been sitting for a few years and I am getting ready to pull engine and repair it. I am looking for input on MoPar grind cams, leaning toward Howard or Hughes. Anyone have preference? Also would you take the whole engine down and have it cleaned for a lifter and a lobe? The build might have 5k miles on it and that's being really generous

Engine Specs I remember... (without digging out a whole lot of receipts)
Stock iron heads
KB pistons
.509 cam
ARP fasteners
M1 Dom single plane adapted to standard Holley double pumper

It's not race motor but it builds good power and right now I need (want) to get it back running. I am tired of seeing it sit. I am pretty sure the cam wasted because of the zinc issue... how do I prevent it from happening again?
