I have a Js manifold for sale.
Ron, incorrect.
With an intake / J's header / decat you will be lean to the point you are in the 14s for sustained duration in the upper mid range. Seen it several times with my own eyes. With an exhaust system as well you will be too lean and will need the ECU map tweaking.

I also wouldnt be aiming for an AFR of 13, 12.5 would be safer.
