This may seem like a stupid question but here goes. valve lash numbers are hot adjustments correct? Ive been setting mine cold .006 tighter since I have alluminum heads. When you guys adjust these things hot, dosent the engine surfaces cool off rapidly and scew your results. I just cant see how this can be done rapidly enough. Do you do one side of the engine and then start it for a while and do the other half. Perhaps Im a little slow especially doing the EO/IC. How do you guys do it and keep it at operating temp.

Thanks Rich
