Is the short head or tall head on the W series better for HP?

The spec for the hitch for pulling, 18 inches high, and 20 back from axle (?), where is it measured at? center of hole?, rearmost point of hitch? and is there a spec for size of hole?

Short head and tall head  are pretty much the same in flow, neither has any real advantage over the other.
Set up your drawbar for 18" at the lowest weight and highest air pressure you plan to run, make it easily adjustable to raise from there so if add  weight or decrease tire pressure you can raise it to stay near your 18" mark.    20" from centerline of axle to the point of hook, most pulls require at 3" loop to pull from , 3/4" thick steel with an inch of steel around the opening.  For your own safety, if you are not required to have wheelie bars, make your hook point  beyond the rear tires .

I'm just wondering if this will end this quickly......(IMHO, which head you use doesn't really matter much, it's what you do with them that might make a difference)
