Call Wells Racing off of Highway 67. I just boom-bitched a set of Trickflow T/W heads when a washer found it's way down number 4 and destroyed the piston and damaged the head. Wells did a good job on mine and charged 75 for the welding work and it looks PERFECT. Call them up, tell them James with the Ford and the washer problem told you to call. They are good guys, they do everything right.
