Mods to stock head

[04ShEeLE]

Is it worth putting a couple bucks into my stock head? Will upping the compression make a noticeable difference on an otherwise stock engine?

Absolutely, probably the cheapest mod with the most benefit.

Definetely!

 

Have .030" milled off of it, power will come on sooner and you will gain 2.5 HP

Great bang for the buck. Lowend torque is increased enough that even the most oblivous rider will notice.

you can just get your stock head reworked and dont even need a coolhead. my builder uses stock head on all his stroker bikes.

Great mod, I had my local machine shop do mine for $25. you want to check your squish band and make sure someone hasn't already cut it. ideal squish is .040, less than that and you'll hurt performance.

I know head milling is cheaper than buying an aftermarket head, but do they preform the same? Also, are aftermarket heads just good for being able to switch your domes up for different compression?

the stock head will increase compression if milled, no doubt, but the compression increment comes along with increased head-cilinder temperature wich the stock head won't be able to cool off, sooooooo go with the coolhead. peace of mind comes first, you know you will be safe.

Overheating depends how you are riding it. The cool head just adds volume to your cooling system. If your heating the coolant faster than your cooling it off it will just slightly take longer to overheat. The same kind of applies to the bigger radiators.

You probably won't have a cooling issue if you shave your head if you don't overheat you bike very often now.
