Well, the results are in! 2 weeks later...
Below are the details of my package. I know, I know you'll are a big fan of MSD which you'll should in every right but I wanted to be the crash dummy and put my hard earn money where my mouth is to see how much potential I can squeeze out of this LT2 Manifold efficiently before making the change. Plus I figured, swapping the manifold & throttle body is a lot easier for me than trying to tackle a heads and cam job when I have Katech locally
I decided to choose the Katech K-Spec Heads and Cam Package which fit majority of my needs. I also added a few extra goodies which didn't come with their package but my budget allowed it for me to get the results I was looking for. Keep in mind, my results is based on 91 Octane not 93 Octane. Based on my assumption, if I put 93 Octane, I would've gain 20-25HP all round but unfortunately Arizona doesn't have 93 Octane.
140HP / 110 Tq over stock is not something I can say "meh" too. That's a huge difference.
I will let a Katech Rep chime in if there are more gains to be had in my package & share more details.
So far I am very pleased with the package. The torque this car creates over stock is insane. I know dyno numbers win the internet but dyno curves tells a different story and its a huge difference between mid and top end. SCCAForums car influenced me alot with my build so at least you can get an idea between the two which both was built by Katech to help sway your decision.
