The 820's have a 114 cc combustion chamber size.

I was mistaken, erik your right, it is casting 292. and i believe they 114 cc combustion chamber. do you know how much my compression is with 114cc chamber,17cc dome piston, deck height-.010, gasket-.020 i just need to know how much to take off the deck of the head, to get my compression where it needs to be. thanks for your imput, erik!
