Head porting and polishing
Good morning Viper fans,
I learned Friday after speaking with the Viper Tech that maintained my 97 GTS for the previous owner that at 3000 miles in '02 he ported and polished the heads and port matched the intake to the heads. He is going to send me all of the paperwork on all of the things that have done to my car. What a great guy. He works at Luke Dodge in Phoenix and his name is Eddy. Can anybody tell me if by porting and polishing the heads I would gain any HP? How much does that cost at a Dodge dealership? He also put on '98 exhaust manifolds as he said they were better than the 97's. Why is that? I've had the car a week now and I've racked up about 200 miles. Most of it from giving rides. It is a big thing here in Klamath Falls Oregon as it is the only Viper in town....at least the only one that is not a garage queen!!!! Thanks Mark |

Re: Head porting and polishing
Generally speaking a port job should give you @ 10% increase in air flow at peak valve lift. If your heads had bigger valves installed you may gain more.

Rob Lauthan is right in your neighborhood. Knows his way around Viper heads and has a flow bench all set up for V10 heads.

Re: Head porting and polishing
Depends if the porter knew what he was doing, otherwise it's slower. If a Viper tech did it...who knows?
