The 58cc heads are a nice swap for some low end power, especially if your using a cam that wants 9ish compression ratio or up. The downside to those heads would be that they cannot breathe very good once you get like 4000 rpm or so. Bigger valves would help, but the price of that may be close to just buying some vortecs.

Either way, its nice for the low end. I would use them.
