AFR SBM Heads, Just got back from PRI

I was more curious about the AFR but a comparison between them would be awesome. The short side (from your pics) does look different but it’s hard to tell if they’re the same casting

The AFR's did not appear or feel any different than the Speedmasters. The ProMaxx's claimed to flow 285cfm I think thats reasonable. The S.S. on the ProMaxx's were not as murdered as I've seen in the past but not great either. I was more excited to see all the stuff for the G3's and there was plenty. J.Rob
