I hear ticking on start up and then go away once the car is warm. I also can hear it ticking when the car is coasting on deceleration. Slight ticking when im giving it Gas until it shift to the next gear, this seem to only happen in 1st or 2nd gear.. I have done headers and exhaust so its possible it could be exhaust leak as well but want to check if anyone have seen Lt4 lifter fail.

Yea, I had one seize in my OEM block last fall. I don't remember exactly which one.
