Big Air/Fuel change adding ported heads?

I just added ported heads to my car that has the forged 355, 847 cam ect. I got the car tuned earlier this year and the A/F was set at 13.1 at WOT. With adding these heads that are about a LE2 equivalent, should I get the car retuned before I got WOT in the upper RPM range? I would assume the car will be leaner with these heads. Let me know what you guys have expierenced. Thanks in advance.
