Since my 6.2 swap, my cold starts just sound terrible. I had many cammed vehicles and never heard them be this loud on cold start.
They are Johnson 2110 lifters, which I heard can be noisy cold. They are quiet when fully warmed.
If it was piston slap I'd just live with it, but the sound drives me nuts enough that I'd replace the lifters if it guaranteed the sound would go away.
This is with exhaust manifolds too, since my Kooks are in for warranty repair.
