as for how to ID the design..... Just the other day I was shining a light into the spark plug holes on my merc and looking at the ski slopes on the pistons

Most loopers will not have removeable covers over the intake ports whereas every crossflow I have seen will have a removeable cover over the intake ports. Also crossflow engines tend to have a smoother idle with a slight rattle sound to them whereas a looper will have a lope to it like it has a big camshaft(unless it is a direct injected engine).
