Headmans are 1 7/8"
I think the Hookers are all 1 5/8"
I have the Hustlers, they are close but I have no issues with heat. I had them coated by Jet Hot and that made a big difference, you can almost touch them when they are hot and they just feel warm.
I have my engine raised 1/2" so you would have more clearence than mine.
