Need advice , 75 360

Ok so I have a 68 Dart GT. The original 318 bit the dust n someone put in a 1975 360. I had it rebuilt. Not sure about all the peticulars I lost the paperwork in this 15yr ( thru a divorce ) restoration. The motor has 322HP with 3" dual exhaust. Thrush mufflers.

Here's the numbers n a pic. 1 what jets do u all recommend and any other info ??
