Alloy used in closed-deck EJ20Gs?

Anyone know what alloy they used in the casting?

Ive got a gouge in the deck surface of my EJ20G block and Im weary about decking it because of the small clearance from valve to piston on the RS-RA setup. I was going to get the gouge filled with a TIG welder, but I need to know what alloy to use
