I wanted to lower the ride height on my car and find the headers are going to present a clearance problem. I have #12 RAIII heads on it and wanted your information as to the performance difference. Also, there appears to be a few reproductions of the originals dubbed "factory headers" is anyone familiar with them? Confused

Headers, especially nice 4-tube items like Hookers, are a good source for a 20-30 hp gain (at leat that's what is usually advertised). They also make a great sound change, but as you note can have clearance issues.

There are a number of "original" Pontiac-type headers that most reports show give nearly the same performance gains as tube/split headers. I would suggest you contact Ram Air Restorations. They are one of our participating Commercial Suppliers who give our members a nice discount on parts. Check them out on our site at: http://www.pontiacregistry.com/index.php?content=affiliates_details&supplier_id=137
