Just the timing chain tension? I assume it is self-centering and finds it's own place?? Thanks

Correct answer... If you use a roller cam you need a thrust button, otherwise the lobe taper takes care of thrust... But a thrust button won't hurt anything & many high performance builds run one...

Okay, so if the cam is always being pulled toward the rear of the block, then what keeps the cam gear from running into the block? Sorry for the ignorance, just trying to understand.
