Who ported my heads?

I have a set of stage vi heads that i bought that have MSC stamped into them. They have been hand ported and looks to be a decent job. They cam with a matching M1 intake with the spacers bolt to the intake. Someone did a nice job port matching the intake and spacers to the heads. The spacers have couner sunk holes in them and bolt to the intake they have pins to locate them on the intake. The guy i bought them off of told me who he thought did them but i'm not sure about it. Like i said any help finding out who MSC is would be appreciated.

i bought an engine with some Stage VI Max Wedge ported heads. the port job looks pretty decent to me but no idea who did it.
