Intake and Exhaust Valve Seat Diameter

[S7ete]

Hello! I'm new to the forum, I'm making a valve seat for my bike which is broken. I sent off the head to get heat treated after some welding that we did on the head (For those of you who are wondering, the valve kissed the piston), Anybody know the inner diameter on the intake and exhaust valve seat? I saw a table from APE, I don't know if its reliable (Shown on the table below).

Thank you!

You can just buy a bare bronze seat from them and to answer your question, pretty sure those all require machining. But jay is super cool, just call and ask.

I already ordered a bare bronze, but thank you. I've already asked jay. Have a good day!
