Your are right Scott. That is why the piston is in backwards. The reliefs are on the exhaust side not the valley side. Look at where the block's locating dowel is for the head. It is in the lower left of the pic. That dowel and the reliefs should be both on the valley side of the block. The dowel is, the reliefs are not. This is a screw up plain and simple. Gary nailed it in post #22. Probability is this is not the only whoops in the build.
