Anyone know how to adjust the valves cold? We're getting ready to toss in this 218 Flathead 6 into a friends car and I want to get the valves adjusted or close to spec before the motor goes in the car. All of the procedures I have found say to adjust the valves with a warm motor. Exhaust valves should be .010" and Intake at .008". Should I run them a bit loose...say .015" for now until the motor gets hooked back up and we can fire it off, get it warm, and then adjust them to the proper clearances?
