Anybody have pics of 426 Max Wedge Stage ll and lll heads

Buddy gave me a 62 , 413 w/ forged crank.413 .060 over is a 426 which is the basis for the 426 Max Wedge. If what I read recently, the 426 Stage 1 was 380 hp, the Stage 2 was 400 which included a better camshaft and 11.1 CR, Stage 3, was a Stage 2 with 12.5 to 1. Apparently the Max 2 and 3 heads were not std RB Or B heads but built fir the 426 Wedges. I would love to see a. Wedge head next to a Hi Po RB head
Anybody got pics. ??
