On a stock US 2.0 liter with the dished pistons...
If the head gasket is removed...no cylinder base gasket is installed. What is the new compression ratio...circa??? Do the valves have a chance of hitting the top of the piston... I have not doe this, so I dont know what it looks like yet...just want to see if someone knows already... Rich |

If your really hot....
bring pistion to absolute tdc...lay straight edge across cylinder and measure down to edge of piston w/ sliding veniers. Subtract thickness of straightedge and you have the deck height. (make sure cylinders are secured). Do for each cylinder. or put modeling clay on edge of piston(s)....bolt heads back on....roll engine 360 degrees...take heads off and measure thickness of clay. Gives you p to h. |
