Doug Thorley Headers Reviews

Reviewed by David C (Moorpark, CA) Reviewed for a 1992 Chevy C/K 3500 — 2007-03-10 06:59:08

Fit and finish was perfect. Hardware for install was changed to stainless because I ordered ceramic coating and did not want to see rust on hardware. I also used copper gaskets from header to head to prevent gasket blowout. A big change in power in pulling range as well as improved fuel mileage. Very happy with overall purchase.
