Just did this to my 351, used a home made oversized valve with welded on blades.
are you doning this with an assembled short block?
I put tape all around the slug and the ports to keep the shavings confined. Shop vac handy.
I also used the same head champer on all my pistons
Don't forget radial clearnce too
