I just recently purchase two set of headers from an estate sale. The guy raced a 68 Plymouth Barracuda Super Stock 426 Hemi. He also race boats. I'm just trying to figure out if they are for 426 Hemi or just boat headers. Or should I just use them for garage item. Thanks
Those are two different headers. The top one does look like it is for a 426 Hemi, based on the bolt pattern. The bottom one may be a 426 header, but it is definitely different than the top one.
Aftermarket alu 426 style heads had different flange bolt spacing based on where the maker located the exaust ports, my last count was that there are 9 different flanges available besides stock
