Re: Re: header coating

  Does a well cracked header really alter the performance so greatly,

Yup.  I managed to make it home from about 100 miles away, at 0300 one
morning, sounding like 4 jet airplanes.  Madge topped out at 25, so it did
take awhile.

or do I potentially have more than one problem?

Always a possibility, even with a "normal" car.
