Well, if you go flat top (most common) you will have 10.4 CR (same as an LQ9). What CR are you targeting?

i think your going to be closer to 10.0 with flat tops and 317 heads (70-72 cc) you would pick up a little with an overbore, but not much, maybe .1
wiseco shows 10.4, but with a 4.100 bore-the high cc heads are what you will be limited by

You need flat top pistons, this will put you at 10.5, same CR as the LQ9. The Lq9 is an LQ4 with flat top pistons and it yields 10.5 CR.
