Hardend Valve Seats?

[Cota]

Working on a set of heads for my motor. Valve resession is a little out of spec and wont allow for a 3 angle valve job.
Does anyone have experiance with the hardend valve seats?
Where can I get them, anyone have part numbers?
I was not able to find any info doing a search so any info would be great, Thanks.

Same here, but sorry no part numbers. I'll see what I can dig up for you.

I got some from WOP a few years ago also.
