I am doing an engine swap between my '56 with the Power Pack option (230cu in with 2bbl carb, 132hp) and my current powerplant in the wagon, a 218 with 2-1bbls and split exhaust. The 230 is running and still in the car. I want to do a valve adjust before I pull it. Keith's videos show him doing the adjust while the engine is running.

The Tech Tips suggest bringing it up to operating temp and then shut it off and do it hot. Others say cold with different tolerances. Thoughts?
