the easiest way is to use an old valve. If you don;t have a valve. drop a bolt with a large head down the guide then a washer that loosely fits the seat id then 3 welds mig or stick are fine about 3/8-1/2 long to the seat and washer. then tap it out.

Thats how I do it....and I have a tig. I take an old valve and grind it to drop into the seat then mig weld mostly on the seat, a little on the valve then tap the valve to pop it out. Hit the seat with a hammer to get it and most of the weld off the valve, on to the next one.
