Full intake cleaning

Full intake cleaning
With so much i time on my hands these days I’ve decided to give my car the tune up it deserves. I was planning on removing intakes, throttle bodies and the manifold to give them all a deep clean with some tb cleaner and some elbow grease. Is there anything I should know before diving in? I’ve never pulled the manifold off this motor, but I have on others. Any special tricks that would make it easier?
Ive removed throttle bodies before, and know not to disconnect them. So I’ve got that covered

Filthy. Saturated with oil. The gunk was really built up down in the cylinder head.
in order to scrape it out the lower mani was removed.
I port matched the upper to the lower.
Smooth out.
Removed casting ridges.
Cleaned up.
f your going through the trouble, remove the lower manifold and port both.
also clean put the gunk from the cylinder head. I had quite a bit. So much so an oil catch can was a must to keep.it clean.
if you pull the lower mani you'll need new lower gaskets.. the upper can be reused even though fsm says otherwise.. also a torque wrench and there's a specific sequence.
like if you have more questions

Very interesting! This is definitely something I’ll look at doing. What grit sandpaper/tool should I use to bore it out? How much room for error do I have if I overbore? I’m not looking to get a tune, would I still see benefits if I don’t?
I’ve already got an oversized exhaust with half the cats cut out so I should expect to see something as there is already more airflow potential
I found a kit on rock auto for like $70CAD shipped, comes with lower and upper gaskets and throttle body gaskets as well. I’ve had those off a couple times and wouldn’t mind getting a fresh set
