"216 carburetors with 235 base"
Swapping throttle bodies can be a tricky business. I prefer altering the stud spacing of the manifold by plugging and re-drilling the stud holes for the original 216 Carter carburetors. Even those carbs are massively too big when running them on a 235 engine.
"going to save myself a lot of time and headache and install the stock intake manifold"
Smart move- - - - -some people are too stubborn to admit they made a mistake. Good luck!

Yup I’ll own it seems to be what I do but knowing how well the engine ran and preformed I’ll put the stock intake back on or at least the correct one before it was a 216 intake with split manifold on the 235 still ran great just flat lined on power on the freeway around 55mph so stay tuned for next adventure
