New LS1 Owners - Newbie Tech - Porting heads

Who/what shop would you guys say does a good job at working the heads? Thinking about getting the TFS 215s FWIW

TFS 215 heads are cnc .you can get them from TEA.

Yea sorry I was half sleep when I typed that. I meant the 220s. Curious if it's cheaper to just get the 220s and get ported or just say screw it and get the 215s thanks
