Also our porting company uses 5-axis CNC machines and CAD software for all projects.

* All pricing does not include the head but based on core exchange, we currently have one 2.0L core in stock

I find it funny that people are surprised. GM flat out told us all quite literally years ago that the exhaust ports on the head where the biggest bottleneck on the stock motor.
Yes, I've been one pointing at the intake manifold, but I've always said after the exhaust side of the head and exhaust itself was opened up.

What exhaust system was used during the runs? ie: header, cat, catback?
Is this a proprietary port profile, or is it the standard M2 Race Systems CNC port profile?(it appears to be M2's "stock" profile)
Does this pricing include shipping??
Is the 2.2L porting compatible the 2007-2008 heads?
Are the valves lapped in the assembled heads?
