There be a listeroid 12/2

As Bob said I wouldn't get too worried about that chip causing compression issues. I would worry about cracks from whatever broke it. Inspect it , grind it down smooth and if you want set the bump .001 close on that side.

Thanks . This head was off before at some point in it's lifetime. There is some evidence of what looks like silver solder or braze repair on one side of the head. Looks like they were trying to fix some tiny porosity holes. Not sure.
I think it was broken then . No marks on the piston or anywhere else. And it definately imo could use new seats. The valves are more like .080 below the head surface. And there is also no valve job there. just one 45 degree angle it looks like.

I'm not near my spec sheets, I'll post it later

I think #1 cylinder has been taken apart in the past for whatever reason. #1 head gasket measures 120mm and #2 116mm. It is the 114mm bore engine so I assume the 116mm gasket is correct. Bores look good. Maybe the 120mm gasket is what was included in the spare parts kit..
I also ordered the George B engine CD. Can't wait to get that.

Don't get too wrapped around the axle with regard to valve depth. If needed, just grind the valves and seats to fit. Adjust the bump clearance to achieve the proper compression ratio. No biggie.
