Valve seats on a Detroit 53 series

Hello All.
I'm working on a 453 Detroit Diesel with 4 valve heads. The engine drank water for better than 10 years so the head needs major work. (BTW, The block is being swapped.)

I've cleaned out the exhaust ports and did a mild porting job on them to smooth out the rust pits and casting imperfections. I'm also going to replace the valves and seats.

What is the best way to remove the seats from the block? I was considering MIG welding a bead around each seat to shrink them. Is there a better way?

Is there a good way to install the seats without the proper DD tool? I've heard about heating the block and freezing the seats but I'd prefer confirmation before I screw up the head.

After the seats are installed will I need to have them ground to spec or will hand lapping be sufficient?

Thank for any info.

Kirk
