Lifter issue - please help
I got done with my H/C/I swap (a few hundred miles since the swap) and i am having a lifter tick, (it gets loud not normal valvetrain noise) driver side on the back maybe 5 or 7. what really stumps me is the tick comes and goes it seams to be worse when the motor is warm, what can i do without taking off the head?

I don't see hardened pushrods, what lifters you're running, or a trunion or rocker upgrade in your list.
I had a tick like that with my YTs that was way high on the motor. I think it was slight interference with the valve cover, fixed by removing and reinstalling the cover and rockers for head torque.

I would think as the motor heats up and the head and block expands ,the distance between the rocker and the lifters grows resulting in less preload.maybe try a little longer push rod.

I don't know, man... I had the EXACT same problem when I did my cam swap. It wouldn't make any noise on a cold start, but after a few minutes of warming up, it would start to tick. It ended up being a lifter on #7.

I'm having a similar issue. I've got alot of valvetrain "clatter". Looks like I need to invest in a pushrod length checker. I also used stock lifters and rockers. I really hope I don't have to change lifters. That means another set of bolts and gaskets.
