Research hemi tick, look up the threads in my sig, rule out exhaust bolts. Always use a top filter, see oil filter thread in my sig, it is indeed half the battle. The wrong filter and the best oil on the planet can still tick, I speak from experience of that exact scenario. Royal Purple 20-820 filter has won the forum over, and then pair a lubrication strategy with that. If it happens right after an oil change it is likely not a mechanical issue but rather a result of the lube strategy either filter or oil. It is not uncommon right after an oil change to have tick, but then as the additive plate with pressure that tick can go away. But there are also options to avoid all of this, read those threads good luck.
