Canadian winters are legendary. I have my shop in an unheated garage with a temperature of -10 Celsius. I’d like to remove some KE4 forged heads, then assemble with new shafts in my warm basement. Since these heads are beloved I’m a little worried about applying torch heat to an ice cold head. Does anyone foresee any problems in doing so.
Thanks

-Bill

Answered question

I’m in Chicago area and it gets cold here. I’ve had no issues with iron heads when removing them in the winter time.
I’ve used propane, butane, and a heat gun.
Built a heat box with light bulbs to set epoxy.
