It should do really well with that combo. Just be sure the first pull is conservative for timing, especially if you go to the samedyno, I'd say 34 total is plenty, and be 100% sure it's all in even if you have to go to 4000 rpm to be sure with a light load, then the first pull's goal is to watch mixture.
Once you get the mixture right, do subsequent pulls with increasing timing. Likely will be around 38 I'd expect when done. Might even want to do a pull with the air cleaner on if you have the time to see how mixture changes. In the car, run that total, but I'd have initial at 14-16 and total all in by 2700-2800. The dyno won't see the rate or initial, but the increased base timing and quick curve will make it far more responsive and happy to drive
I am not sure your numbers will go way up from last time, in the end, as good as the CJ heads and intake are for stock pieces, they have their limits without significant work when you add cubic inches, but I bet it will be one of those engines you fall in love with in the car. However, you have a very good match there and the dyno can't read
