Nothing is decided yet.
You have to have them in front of you, they sank the valves more than I've ever seen,
Other option is a serdi 5 angle cutter to make a better chamber side radius.
Shop sank the valves to use the eddy springs is my first guess. That hurts these heads and you lose potential. I would have bought another set of springs, not sunk the valves flush with the chamber....cause that's what we are talking about here.
