ive heard ford racing stg 2s are really good for daily driving.

the fr2's work great for daily drivers ( they are quite docile) , i'm actually thinking about going a little more agressive this winter myself[thumb][}]

What's the effective RPM range on the FR Stage 2's and does it make the engine an interference engine with the stock head, valves, pistons, etc?

It does not make the engine an interference engine, but could be wrong
the FR2's are making power throughout the entire power band. Less
at the very top end (6500 and up?) but daily drivers dont
see the end of the power band too often (not counting
mashing the gas) . You will notice a big gain in the power,
even more so when you free up the exhaust with headers and
full exhaust. Happy endevours and if you have any more questions
just pm me.
