I have a hard time you've been a dev (or any career) where you don't know that intermediate comes between beginner and advanced. If you look at any standard career ladder:
* L0 jr software engineer
* L1 jr software engineer II
* L2 software engineer
* L3 software engineer II
* L4 sr. software...
You can get definitely exact mounting bolts at home depot or lowe's for like $3.00. I did this, you can also get fancy titanium ones from TitaniumWorks if $100 bolts is your thing.
It's late and I'm tired, but the short version is no. You don't need to change any other heat exchangers to reap all of the benefits of an aftermarket intake manifold.
