Tighten up your helper springs until you can't get the head on the ground and then back them off a little-depending on tire size they should be 10-12 inches ahead of fitting on each cylinder-trust me they HAVE to be tight!!!!!!!!!!
There should be an oil cooler attached to a pull up box between the air screen and the radiator on all F2's with automatic header control. I had to replace mine four years ago at a cost of $450. My header control is electric over hydraulic like the F3 has and I have no helper springs.
