Gary Stauffer of Quality Engineered Components is making header flanges for our '56 Dodge 315 Poly V8. I believe these will also fit the '57 325 Dodge Poly and maybe other years as well as well. Gary goes by 73RR around here and is a god guy (thanks for the help Scooter!). Man, its a small world! Its been real difficult for us early Mopar Poly motor guys to get headers for our motors as most companies only build them for the Hemi heads. So if you have a Dodge Poly 315 or 325 and would like a nice set of headers, give Gary a call and order your flanges, then your exhaust guy can finish making the headers. Gary may have other years and makes of flanges to fit your engine as well. Jay
