Pistons

I caint let this go. Your pistons are in WRONG. Look at the valve arrangement on your cylinder heads.

The valves are arranged as follows:

E, I, I, E, E, I, I, E

Now, look at the arrangement of the valve reliefs in your pistons.

E, I, E, I, E, I, E, I

The valve reliefs should match up with the valve arrangement of the cylinder heads. Yours DO NOT.

Now, look CLOSELY at the diagram YOU posted from United Engine. Those reliefs are arranged E, I, I, E, E, I, I, E just like yours SHOULD BE, but ARE NOT.

Now, if you continue to argue after this, you deserve whatever you get.
