We used some stuff then, because we HAD to. Today, I wouldn't waste the time to grind on a set of 906s. I also didn't use those heavy azz TRW slugs then and wouldn't now. Also cam technology is better these days as is everything else...........So to answer the question I suppose, no, I wouldn't build it today like I did then. I see no reason to. Embrace whats available, don't be lost in the past
