Heads Up! Pondering Info?

dartjack,
The small quench heads are very good for street as this is what they were built for, to help emissions and make more power in the low rpm range and more torque. Just stay with the stock size valves and do some work to the heads and it should be way more than what you will need on the street. A small cam will help alot with the torque and low rpm HP and it should be good to 5000 rpm's, open the bowl area up and gasket match the heads and you should be set.
