9.5:1 -how much to shave off?

[matty8]

have a 165kw Vp does anyone know the std comp ratio?

how much would i have to have machined off the heads to acheive around 9.5:1 or even higher (i will get a crow cam kit ,stage 2 or 3, soon and want the comp bumped up)

would even higher (ie 10:1) be better or would it run badly with the crow tune? if better how much would need to be machined off?

any info would be great!
