Otherwise in an out of stock application or anything that isn't trying to max you mpg on the street the heads are pretty much worthless.
So vortechs and zz4 l98 heads are about the best in terms of factory performance and price. The l98 head would be the best with the 58cc chamber and 175cc runners

Bigger better badder, mmmmmmmmmm.
If the carb is too big or not adjusted/jetted properly it can dump too much fuel and cause boggs and hesitation. Dumping too much air with out fuel or visa versa or too much of both can definitely have an ill effect on performance.
One thing I haven't seen discussed is fuel pump and pressure. Which I don't think is gonna be an issue unless there is something wrong with yours.
Maybe I missed it, what carb and pump set up are you running?
