No i finally replaced them but it only took about a 1000 miles before the car started smoking.ANd it just got worse and worse, But i needed to replace a head gasket (lasted over a year and started to push out of the bottom) so i had them replaced only to find all my exhaust valves were warped on the seat. BUt hte good thing was the car made 437 horsepower, Changed the guides, the valves and put on a set of headers with hte same boost it made 540 at the rear wheels. I really do know exactly were all the power came from but it sure wasnt there before and the car would only pull to 5100. Now it pulls to 6000 and has by accident a few time seen 6600.Originally posted by Two Lane
