Misfire after installing Crawford Billet Power Blocks (BPB)

So today I installed the Crawford Billet Power Blocks. I took the car for a drive after I installed them, and everything seemed normal until I revved it to about 4k under load, and it seemed to stutter and not want to go above that. I took it home and tightened up the intake tube and looked over everything and it all seemed fine, so I took it out again and under a bit more throttle revved it to 4k. Same issue, but this time I got a blinking CEL that went away after a few seconds. I checked the code with my OBD reader and it's a cylinder 2 misfire. Any idea of the quickest way to fix this or find the problem? My guess is the o-ring on that cylinder has come undone and is causing a vacuum leak. Thanks in advance

By the way - my only other mod on the engine is the Perrin CAI and inlet tube. No tune.
