Yea, if youre taking the motor apart, I'd just build it. You forgot a lot of miscellaneous gaskets/nuts/bolts/etc. I just replaced every gasket for the exhaust manifold to the cat. Theres quite a bit of nuts/bolts you may need and while it doesn't seem like much, it adds up. Personally, i would move the boost controller up to priority 1. You may or may not get to your goalswithout it
