what about sbm victor heads

"standard rocker gear" can be a bit misleading.... I'm certain they would have been offset rockers similar to the W5/W2. One of my questions that went unanswered was as to whether I'd be able to use my Erson 1.6 rockers on them. They "thought" yes, but a final design hadn't been decided on. On paper it would have been a good head to fill the void left by the W5's and been a better casting to boot.... or at least that is what was conveyed to me. I imagine the biggest hurdle was figuring out if producing this head would be a good investment. Apparently they thought not.
