1F Engine cracks in cylinder valve seats

[Wanhis]

I took my cylinder head to machinery shop. During the operation, operator noticed cracks in three valve seats. Are you able to change/drill/weld those in this engine? Cracks might go wurther to water side.

Thanks in advance.

Machine shop should be able to determine what's needed, that's what they do

+1 for hardened seats for no lead gas. You might consider chevy valves.

Any competent machine shop should be able to yank those out and install a new set of seats. The valves and seats are technically wearable items with a usable service life.

Do not try to DIY this though.
