Odd Head options for Turbo engine.

HI. Im getting ready to build up a L28 for my Maxima wagon to replace the L24e that I've turboed.  It will not be a high horsepower build.  I have the stock MN47 head and I have a N42 head.  What are your thoughts on which to use? I know the logical answer is sell both and buy a P90.  But lets just say I'm odd and like working with what I have.  I do have the ability to run E85.   Looks like with the N42 I would have a compression of about 8.2:1  and the MN47 would be 8.97:1.  Running Speeduino ECU with COP .  

just thought Id see what your thoughts are on here. The MN47 is currently running on the L24e engine with about 7 PSI of boost. But is pretty laggy due to the stock Torque converter and only being 2.4l pushing the Turbine housing that was used for the 2.8l.
