With the ARP studs already there, you're good-to-go on polylocks.
You may want to get one of the shorter-styles and make sure you double-check your clearance to the valve covers.

We've used double Ram Air IV cork valve cover gaskets (5/16" x 2) to add clearance when needed.
They also make valve cover spacers in various thicknesses, but your clearance to your brake booster can come into play.
Good luck!
