I have a 98 Prelude non-sh which is my daily driver to work. What would be the average cost on a stock rebuilt for the cylinder head??

 

It's hard to give an estimate because it depends on what is wrong with it. If it only requires a resurface and a couple new valves, or if the whole valvetrain needs replacing, or the valves are leaking...

Anywhere from $1000 to $2000 is probably your best bet. Buy a used head for cheap.
