Super Jet What spark plugs to use?

[sj650bp]

Putting a Riva non girdled head on my 701. The spark plug holes are much deeper than the stock head. What plugs are recommended for this head? Do I just get the ES plugs? Thanks....

even though i use an ADA head i think the same plug can apply
i use BPR7ES
i go with a hotter burning plug for the longer no wake zones and the fact i am on a heavy oil mix, not to mention i also had a supply of BPR7ES plugs
i also use solid top caps as well and gap 28
no problems with the setup
i like the projected tip which is what P stands for
