I bet your valve was bouncing and possibly caused that seat to chip.
Regardless again maybe my eyes are playing tricks on me but.....I think that seat chipped from what I can see.
It would be interesting to know how many angles were used for the valve job and what degrees were the angles machined at.?

It would be extremely interesting to know that as well. TSP will not tell me any of that info, I mean I kind of get it as some might be "proprietary" race info, but then again we are paying them. I can't even find out if they use stock seats or put their own in or what.
So found more things, #5 exhaust valve appears to be bent, it was hard to take out, and I put another cylinder exhaust valve in and it went in easy:
Also, every single other intake valve, #5, #3, and #1, all have this same chipping or burning or whatever it is damage:
So I was thinking with an aftermarket casting I could get a smaller combustion chamber but apparently not the TSP one only goes down to 54 CC chambers. I think I estimated I was around the same 55 or 54 CC or something like that with my .030 mill. My dream build is very high compression E85 motor but everyone I ask gives me a lot of negative feedback or the "just put a turbo on it".
