Head Gaskets

I am wandering what anyone is using for head gaskets on a 340 with the block o-ringed. I purchased a 340 short block that was built in the late 90's, started but never ran much. Had W-2 heads on it that leaked, so a couple cylinders have stains in them. I am going to try to clean it up, check the clearances, and reassemble with new rings. Now I started working on it I see the block is O-Ringed, and wasn't told that when I got it. It was in pieces when it got dropped off. Will a 1008 Fel Pro work?
