Wouldn't you need a soft tape to measure the rollout like that? Or wrap a rope around them and measure the rope?
I would think that tape would leave some error
I have a set that have a nice cracked out front bolt hole that could be fixed and painted. Silver fullbores. Idk if you would be interested in a project set

What carbs, jetting, altitude? Running to rich can make you over heat. I'm no jetting pro but this info will help others to help you. Also any porting and what other supporting mods?
