I am running a set of ported iron head castings...I could always shave them a tad to raise the CR, if I was to do this, what would you recommend to aim for? 10.5:1???

Yeah, I'm sort of trying to find an "excuse" to try the hydraulic roller...... my next build is going to be a 408" W2 headed stroker so I'd rather expriment on my current setup and learn a thing or two before I get to the stroker build.
