Not sure if you were refering to my post with your rant? I edited and added " cold" after .019 for clarity. Nothing was said about cold to hot lash change. My whole post was about learning what will happen when deviating from the lash settings on the cam card, and also what CAN happen when checking lash in different spots on the base circle. Probably not terribly critical with lower spring pressures, but there will be some change. And if you are pushing the limits,,,,,,
On my race roller the cam grinder said DO NOT go more than .002 in either direction from cam card lash settings. That requires that I am very carefull about how i set lash to stay in spec.
