Yes, the angled plugs are all part of the master plan. First a few more details. Like I said above the head of the pistons will be a mirror image of the head. What I did not say was that the shape of the piston under the intake valve will be domed, and the shape under the exhaust valve will be dished. The idea is to use the domed portion under the intake to make some squish which will force the charge to the exhaust side, right where it needs to be to flow out. The angled plug will now be closer the true center of the mixture, just like you said. You just have to imagine the chambers are no longer traditionally shaped, they will now be offset towards the exhaust valve. So, a few things that will make this work. First all of the chambers are designed in 3-d on Pro-Engineer, so it will be easy to design the piston tops to be exactly a match to what I am trying to do. Second, since the chambers are all CNC machined at one time, they will be perfect in shape, size, and volume to perfectly match the CNC’d piston heads. I am hoping the small tight chambers from the above idea will make for a very fast burning set-up, which means less detonation, and less timing. All good things.
Check out the link I posted above, It goes into much more detail
BTW The head above (P90) is just roughed out. Once the head is surfaced, and all of the valve guides and seat installed, it will be put back in the CNC machine and cut to its final depth with a much finer step-over
