if its not a daily go bridge port, in reality you would want a boosted motor for the altitude to make up for the lack of air since your car will become slower as the air gets thinner during a hill climb. But since your sticking NA go with a bridgeport your going to need all the air you can get in there towards the end of the run.

I would go about balancing your rotating assembly too if your going with an rx8 E shaft, its not nessecarly for most applications but unbalance can rob you of power at higher RPM and cause unwanted flexing.

Go with an exhaust port comparable to your intake, you can get your torque band where you want with exhaust tube/header/collector tuning
