First of all, this is not a mild build...
I like your plans so far. One thing is that you need to check a injector size calculator becuase I think that you will need injectors that are larger than 32lbs/hr. You will likely need something in the range of 42lbs/hr. As long as you are putting in a new rear & swapping in a 6 speed, you will be very happy if you swap in 4.10's for the build you are doing. Other than those two points, you will be very happy with your plans.

Oh, well that's why I said to use a calculator, just to be sure. I also forgot to mention to perform a compression check to make sure that the engine is healthy.

The Headers seems like the weak point, if ur tryin to maximize everything seems like LPP LT are a bit better for the same price just harder install, I"m gettin ready to do about the same stuff on my car and I'm droppin the K member to do all this just seems like much easier access, you might wanna consider the same thing.. On the TB/injector size stuff seems like everyone has an opinion on that stuff, I'm gonna use a 54mm bored out deal I found on ebay and prob 30lb but I'm not using the stage2 heads or that cam.... Good plan otherwise, what clutch you gonna use on that setup?

im not liking the llp headers. seams to be some fitment issues and rusting. I will wait for the next batch and see if they are any better (also not liking the stepped design)

Texas speeds headers look good also
