20psi boost

The stock hg is good to around 12psi from what i've heard, but don't hold me to it. But I believe the two reasons to get the head shaved are because the head is not flat enough or to make a smooth surface for the mhg since it needs to be as smooth as possible. So as long as you made sure to clean the surfaces and threads well then you should be fine with lower boost levels. But as far as your torque spec, I assume you mean ft.lbs.. Did you use arp head bolts , because that spec seems high even for them? I did 90lbs on my studs with the moly lube. Also did you follow the patten for tightening and do it in three passes?
