DONT wrap it around the head.
The longer you go from the tank to the intake on the mill, the better the chance of surviving a flip on the track and staying running. Dont go too long. I coiled mine 1 1/2 times under the tank and thats it.
As far as the backpressure line goes, keep it as normal as possible. The shorter/longer this piece is, the more tuning you may have to do to accommodate it. Keep it as close to stock as possible.

The fuel line lengths do make a difference.
The fuel system is pressure fed from the exhaust pipe, through the tank, and into the carb. The lengths of the line pipe to tank and tank to carb should be between 8 and 10 inches in length for each.
Going shorter on the length for the run from pipe to tank will overpressurize the tank and in turn force feed fuel to the carb causing a rich condition. Going longer on the length for the same run can underpressurize the tank and cause a lean condition.
For the run between tank and carb, the longer the line the longer the engine will stay running while the truck is inverted...but you also run into a lean running condition. Similarly, if the line is shorter you reduce the time the engine will remain running while inverted and you create a rich condition.
As for winding the line around the head...I don't recommend it. First, you would need to heat shield the fuel line to keep it from melting. Second, even with the heat shielding, the heat from the engine would most likely vaporize the fuel causing the engine to run lean and eventually die out for a lack of fuel.
Hope this helps.
