It is cost.  Think of the BTU's of gas needed to heat to around 800 degrees slowly through a couple of cycles when a broken in engine would do the same.  Do a search on ceramic coatings.  It is interesting reading. ----- Original Message ----- From: Dale McIntosh To: [EMAIL PROTECTED] Sent: Sunday, August 17, 2003 10:18 PM Subject: RE: [Chevelle-list] Need a set of BB headers Cost probably.

Seems to me this would be something I would do if I was making them.  ����� ..............  ----- Original Message ----- From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Sunday, August 17, 2003 6:08 PM Subject: Re: [Chevelle-list] Need a set of BB headers I'll chime in on this one.  I heard something about this last weekend.  Breaking in an engine will do something to coated headers.  I think it will fog them really quick if I remember correctly.  I bought a set of the Dynomax ceramic coated headers and put them on a fresh big block pushing over 500 HP, and they fogged within a week.  I would follow the directions and not use them on a fresh motor.
