These lifters do not look stock
I bought a 2004 Z06 1 year ago. Thought the engine was stock. I was diagnosing lifter noise and removed the lifters to find these in the picture. They do not look stock for a 2004 LS6. Also, the head bolts were 2 different sizes. According to ARP, the large bolts should all be same size for 2004. Now I think the engine is not all stock, but I think the engine has never come out based on my removal of the transmission recently due to all connectors and wiring being in 100 % stock location and condition. (usually some brittle plastic breaks, or clips dont get put back excatly)

Looks just like the ones I took out of the LS6 short block that I just put in my car.
