I am trying to work out compression ratio of my 2056 build. In calculating head volume my understanding from the forum is that stock 2.0 heads have 57mm and the valve pockets on the pistons I am going to use is 3mm. Do I add these together to use 60mm in my calculations for head volume?

Ended up at 8.8:1 CR Never pings, run on high test and pulls nice |
