What kind of power are you making now with the E85 and CAI? If your going to port the intake also do the TB. I'm doing a similar build with E and Cai, cat delete but using the stock exhaust manifolds. Gm did a pretty good job on the exhaust for the LT1s. On my Camaro I just sold I made well into the 700's on the stock exhaust with the 2300 Maggie, stock Lt1, did use Meth/water for extra fueling and Lingenfelter Big Bore Pump which was basically a modified LT1 Fuel pump a few years back.

+3 on above Look at MAP Performance for the ported intake manifold-
However I would start with the easiest mod 1st which is the intake manifold Then the headers
