Yes I think 7500 will be the shift point power is still good at 7500.

Did not flow heads but have done so many w9s they would be in the 360-370 range
Exhaust would be in the 250s

This has small 2.15 intake valve and exhaust valve with wrong shape.

45° valve seats. (Not what I normally use on w9) but locked into using valves and no margin to change seat angle.
