I checked the cc on the piston by wrapping it with saran-wrap, then packing tape and then sliding it down into my 4.360 ring compressor to keep it level and still. I put my 20cc's in my syringe and it took 20cc to fill it up. I can't control the bubble effect that goes above the surface but that would only account for 1 or 2cc's so they are at least 13cc's.

My 3 options are:
- Deck the block or use .020 head gasket
- Surface the heads (Scott Koffel said .006 was worth 1cc so I'd have to take off .060 and .060 off the intake)
- Remake pistons

I hate having to wait another 6 or so weeks but I think that is the option that makes the most sense.
