Cranking compression on 1996 RT/10 with head work

[Viper Scot]

I was wondering what sort of cranking compression (psi) I should expect on my 1996 RT/10 that's had 'stage 3' (is there a standard to different stages?) head work done? Presumably higher than the standard?

My stock 96 GTS's warm engine, W.O.T. cranking compression averages 177psi. Milled heads will raise this number.
