Deck height
Your deck height figures out to be 9.582" if they did it right on the money so the KB's should stick out of the hole .006". You should be fine if you run a .040" or thicker head gasket. Only thing you might want to watch is the compression ratio. It can get pretty crazy high real fast with a 4" stroke and the pistons sticking out of the hole. Especially if the heads are closed chambers and/or the pistons are flat tops.
