I don't think you will have a clearance problem with stock manifolds.
Some headers might be tight..
A different concern...
I would look at the alternator mounts / accessories to make sure your belts line up...
Another issue may be the height and air cleaner / hood clearance.....

Seriously???? 1/2 an inch wider flange on a 23 degree head? On a motor that makes only 390 hp. If that’s the case I would seriously look at something different.
Might have clearance issues with the exhaust pipes, etc etc.
