Valve Seat DIY Replacement

@PRH I just got the heads disassembled and I see what you mean. Definitely different than LA heads that I'm use to. If all I need to do now is open up the area to 89% of the 2.02 valve to make it effective could this be done via a neway cutter? Or maybe neway sells a bowl hog. I've used their cutters in the past to do a 3 angle valve job at home but not sure if they have something to open up the area this much.
