What are you doing for a cam, and where do you want your cranking psi to end up?
I wouldn't really get obsessive over having machine work done until you plan out where that's going, because static compression pretty much means dick all (flame suit on). The cam is where the action happens, and if you're going the custom route you have a WORLD of possibilities that are open to you in attempts to negate machine work. Evidence of this can be found in many cars landing around the 195psi mark (about the pump gas limit) on a myriad or static CR's. Conversely, the example that 70rs alluded to shows just the opposite -- I don't know the combo he's speaking of in detail, but I bet it utilizes an OTS cam and it's bleeding off a ton of psi.
Lots of variables to keep up on.
