Compression on phase II/phase I hybrid?
I have a '05 phase II short block w/ a phase I DOHC head milled to max OE tolerance, ported/polished too but I digress. I recall plugging in some values into some spreadsheet that's floating around a while ago and my CR being about 9.6:1. Is this accurate? What do you think my CR would be in estimate?
