Nah, unfortunately I do not.

I initially had the heads at another shop that does have a SF-300 bench and we were going to do a step-at-a-time "do and check" kind of a thing with these. But after waiting for months and never having been able to get any traction at that shop I gave up and just went my DIY route.

So I do have the "new in box" numbers on that SF-300 bench, but it's not the same bench as these last numbers, here they are:

LIFT - INTAKE - EXHAUST - E_TO_I_%

0.100 - 066 - 074 - 112
0.200 - 120 - 135 - 113
0.300 - 160 - 170 - 106
0.400 - 203 - 186 - 92
0.500 - 234 - 200 - 85
0.600 - 252 - 200 - 79

What you can tell here though is that while the INTAKE side does seem pretty reasonable, the EXHAUST is actually higher in as-is shape than it is after the porting work. Not saying that's wrong, but the casting flash in the as-is port really narrowed down the throat area, meanwhile the porting work simply removed that excess material and barely touched the bowl itself, so no actual reshaping of that area.
