340 Aluminum Head, Rocker Arm Upgrade

I am about to install a port injection setup on the '72? 340 motor in my '67 Barracuda and would like to upgrade the headers, heads & rockers at the same time. I believe the motor is mostly stock, gauged just by it's power output.
1. Are there any aluminum heads that are clear winners over the others? I would like good heads I can use right out of the box, and upgrade them to use on a stroker motor later on.
2. Any idea how the 65 cc aluminum heads compare to stock heads from 1972 or 1973?
3. Would it be a good or bad idea to use 1.6 ratio rockers to increase the cam profile without touching it? If so, what rockers do you suggest?
Thanks in advance!
