Thank u for responding ok has a new hod rod crank was bored over not sure how much and not sure if it was milled I called the guy who built it and no call back but I put piston all the way down in the stroke and it looks like its perfectly level with the exhaust port
Does the edge of the piston rise above the top of the cylinder when the piston is at top dead center? If so, is the hole in the head gasket large enough for the piston?
If the piston will go through the head gasket is the step in the head at the outside of the squish band larger than the piston?
