cleaning up the slant six head

One more question along the lines of head porting for dummies. Can yall give reccomendations on the neccesary supplies, grinding bits and actual grinders themselves?
I plan to do this work myself, I will be posting pictures along the way and asking for corrections suggestions as I go. I think you and I will have a pretty good understanding of the basics by the time I am done.

Tools and equipment are no issue for me but its easier for me to post pics which I will be doing after the next couple/few weeks.
