That is killing it! I'm guessing, that's around .700 or so lift? I'm looking forward to the numbers you see on those compared to the CNC flow numbers on the head flow chart.
I posted all of those numbers last year on my Speedmaster heads. And as far as valve size I flowed the 360-1 heads on my 422 on the same fixture and it’s been five years but don’t they have a 2.015 valve.
