I'm waiting for someone local to let me borrow their car
for a few days so I can offer a "full bolt-on" tune to accompany the rocker setup. It's not the cheapest setup, however it's an easy afternoon swap, no tuning required (but recommended), and absolutely 100% as reliable as a stock motor. 1.7-1.9 ratio on the intake, exhaust likes a 1.6 or 1.7.
