Also, ceramic coat your headers inside and outside. Better still, do your sidepipes outside too. This will dramatically reduce the underhood heat generated by your exhaust system. Had I known this was going to work as well as it does, I would have used less insulation in the foot boxes. With double face aluminum padding in the front end of the pass compartment, and the ceramic coated headers, the footboxes and firewall don't even get warm.
