I'm putting new headers on my fox today and am not sure of what to torque the bolts to? Anyone know where I can find the torque specs for a 91 ford mustang gt. Or better yet, does anyone know the specs themselves?
Honestly, I don't really use a torque wrench on header bolts, but I'd guess 15 ft-lbs would be plenty. They should be retightened after several heat cycles. Else, you are likely to have a few header bolts back themselves out.
