X-Head Porting....
@PRH I dont know what exactly the SSR is... but I think I found found the heads @RAMM ported that you referenced and they were for a recent 416 build. He was able to get 263 cfm max on his bench.
Just from glancing he didn't take much off the sides of valve guide (?), imo. It looks like he shortened the valve guide down I think he said 3/8in or something along those lines. (please don't beat me up if you did take a lot off and I misrepresented what you really did).
I'm posting them here so I and any other people can look at them. I'll also repost the other ports from another thread I think a guy in Europe did named KMA..
First pictures from RAMM and last ones from KMA
