Just the way the molds were made. This causes a bad fit with the header tank, which I chose to fill in with flox. I taped up the header tank joggle with duct tape, and spread flox on the longeron joggle and molded them together. In some places, the flox was several mm thick. I would not use heat to "straighten out" this area. Just use flox to make the joggle fit together, then use whatever filler you are using on the exterior to make the exterior blend together. If it makes you feel any better, I had a lot of trouble with this area, too. The fit of the forward deck to the firewall is not critical, since you will be applying bid tapes to the forward face of the firewall to support the deck, once you have it aligned with the cowling. You will have to drill a couple of temporary holes for clecos in the header tank to longeron joggle to hold the tank in place while you align it with the cowling. (Of course the engine and spinner need to be in place to accomplish this.) When you have everything aligned, you apply duct tape to the underside of the header tank where it overlaps the firewall, then put in you 2 or 3 bid tapes up underneath. These will support your header tank and cowling when they set up. BTW, I used nutplates and #8 screws to attach my header tank to my longerons. Due to all the flox buildup on the longeron joggle, the length of the screws along each side varies by several dash numbers. --John
