Thanks for the comments. I did all the disassembly/assembly work myself aside from the machine shop stuff. The reason for the quick turnaround is that there is an upcoming race event at the end of the month that I must attend in order to keep up with points.

If I say that, it would be the second engine I would build. 
Thanks! I plan to recalibrate the O2 sensor and reprogram the MTX-L wideband to the standard LC-1 parameters of 0V=10:1AFR and 5V=20:1AFR

I just went out to break the engine in. I used the FM break-in method. The engine runs smooth and feels great. I disconnected the coils and cranked the engine until I got oil pressure before starting it. So far, so good. I haven't found leaks of any kind.

So far so good! I have been driving the car as my DD. No leaks and no problems. I have made some changes to my timing and fueling for safety's sake. I have also re-installed my boost controller as I can hear the forge actuator opening up at 5PSI.

The next track event is this coming weekend. So far so good. I really want to dyno it first, but it looks like it may not happen. I plan to dyno it soon. The car pull hard and idles well. There's no smoke and it has good vacuum.
I tried reprogramming the wideband output range to 0-5V, 10-20AFR to see if I can get it to match the MS in Tunerstudio, but it was always a point off in the software. I set it back to default then tweaked the lower AFR value in TS and they do match now. The default values for the MTX-L is 0-5V, 7.35-22.39AFR. I set it as 0-5V, 6-22.39AFR in TS to match.
I have the boost controller set to open at approximately 10PSI. I may have to tweak it some more and/or install a softer spring in the MBC. I am currently using the softest spring in the Forge actuator. I have the rest of the spring set ready to use if needed.
