I have done many valve jobs but at this point don't want any more surprises,
the place that will line bore the block will do the seats again, but only by making them larger.
To me that is out of the question if there is any other way.(I've been reading too much fordbarn,is that possible!)
I can make a tool that will pull them straight up and out then reinstall and peen.
I am confident that I can pull that off. And the question of valve seat adhesive, can it later deteriorate and leave things loose. And exactly what brand,,, many shops don't use any.

Am I out of my mind or what! Don't ask the wife!

Never try to use the same O.D. of valve seat that has been tried, and pulled. We have never had a seat come loose or out. You just have to know the right press clearance. I have a machine shop in Fort Dodge, Iowa do that kind of work for us, and Vern's work there is perfect, and I do know what perfect is.

Here is some of his, and our work.
