Help! Intake manifold won't fit!

So guess what!? I actually do have a hole that the temp sensor fits in! I thought it was blind hole but I put anti freeze in the car and guess where it came out?
Got the reducer on order (I wanted a black one). Thanks so much for everyone's input and sage advice. A few picks of the almost finished product. Now for the Doug's D453', Edelbrock AVS2 500 carb and it will be a runner!View attachment 1715519473 View attachment 1715519474
I feel like a dummy! I just need to tap the hole to get paint out of it and it should be perfect.
