413 Wedge

Me and a buddy just rescued 2 '65 300's with 413's. one for me, one for him. He also picked up a 426 long block with the deal. My buddy (mid 60's with a thick skull) swears up and down that the 413's are all "street wedges" and that they are valuable.. I told him that they have wedge shaped combustion chambers, but they are not "wedge" engines and should not be considered valuable. I have no idea where the "street wedge" name even comes from as I've found no information on that terminology.
The Street wedges were 1965 426 RB engines with 10.3/1 compression, a hydraulic cam and a single 4 barrel. The Max Wedges were 12.5/1 engines solid lifter cam, and dual 4's as well as the special cast header type exhaust manifolds. The 413's came out in 62 and in a single 4 barrel as well as a Maxie dual quad version. If any of these 413's or 426's were a single 4 barrel They weren't "Max Wedges" I see some of the 300's had dual quads and dual point distributors. . Do your homework!
