All cylinders filling with water

Update.......Both heads with new head gaskets are on and torqued at 35 right now. I will torque again tomorrow morning up to 70 then tomorrow afternoon at 110. Dowel depth and diameter is fine. Studs look great, with plenty of room to tighten them up. I sure do appreciate all the help.

Is there a reason you are waiting to torque the heads? I always finish them up right then making sure to do the proper sequence.
What gaskets are you using?
