You can take them down .030 which is about 5cc's and the manifold still fits.

How much should that bump the compression up?

Mine were milled .020. I was told it raised compression by 0.5 to 0.6 higher. My Lq9 flat tops are 10.8-1 stock i believe. so that should put me at around 11.4-1. Someboby correct me if im wrong please.

Default Boost?
If you plan to boost, don't mill them...
