who does best port work on dart steel heads 23 degree ???

If I wanted anything ported I'd call Curtis Boggs at Raceflow Developement.I've never had heads ported but his reputation is excellent on any forum you read.

RFD, Curtis is as good as it gets.

Just thought I give my 2 cents worth on this question.
Rhyne engines (in Gary Ind. I think) has a great reputation and build nearly bullet proof motors. When I was racing all the front runners used Rhyne.
