This thread has gone all weird lol! I've noticed some company's are selling the 1.2mm s/s gasket as a stock replacement after a light head shave and torquing back down. The result of this on a otherwise stock 7mgte jap engine that had done 120,000klms was a compression reading of 180 psi average across all 6 using the HKS 1.2mm gasket. Yes no two motors are the same, treat this as a rough guide.
Also there is no way to tell if the ma70 you own has bhg'd several times and has been shaved more than a pornstars box.
