Default Running issue need some help

Hi guys just wanted to say thank you before I get ask my question.... Car is a 98 trans am that I did a cam and spring swap and everything ran fine.... I decided to buy some 799 heads and have them ported and a valve job done... After installing the heads I went ahead and installed a fast 92mm with 92mm throttle body and now the car is running like absolute ****..... popping and running like it has a miss I have a video if anyone would like to see or point me in a direction to start looking at...

Not yet almost sounds like a vacuum leak and beginning to think the fast intake isn't sealing correctly
