I'm going to buy a dart block 2.0L from this place in Cal. The person I buying the block from is going to do the complete block (crank,piston,rods) I was thinking about going with 13.5:1 but the guy didn't recommend it. So my question is what ratio piston should i go with?

Aem cam gears

Things I need to fin.

Port and ploish the head
