Valve lapping

[bosstime2]

Do these look right after lapping?

Those look okay for a hand lapping job. In the first picture, where we see your foot, the lapped area has a ring in t. I’d keep going until that ring is gone.

How are the valve seats? The valve is only 50% of the equation, the seats are the other 50%. The seat face needs to be just as clean as the valve face.

Second one looks too wide to me.

Two of the seats don’t look shiny yet….i guess I’ll go a bit more on these. Thanks for the insight

Shiny does not seal as well as the graying you have in your pictures, I found this out when I was working in an aircraft engine shop 50 years ago

Years ago when I had just bought my first Model A, an old timer (then because I was 15 years old) told me to lap the valves then mark the seat with a pencil lead. If the mark disappeared when you spin the valve, it was perfect.
