This is a very good question. I have had experience with both.
I have a 98 Banshee and had the head removed and shaved. Up until then, I never had any overheating problems. Once the head was shaved, I noticed that I ran a little too hot even though I had re-jetted, opened the airbox, etc.
I then installed a Pro-Design Coolhead with 18cc domes. It never runs hot now and there is a definate increase in power (and operator confidence).
Go with the Coolhead. It is really only about $150.00 more once you pay to have your head shaved, polished and a new gasket. What you get for that extra money is a much more reliable engine, more cooling capacity and a bitchin' looking engine.
By the way, regardless of which way you go, you MUST run Racing Gas (I prefer VP products). Octane boosters are not the same thing. You need atleast a 50/50 mix of racing gas and premium pump gas or you will get too hot regardless of your jetting. The compression is just too high once you start messin' with the head.
Go with the Pro-Design Coolhead. You will never be disappointed!

Oh yeah....make absolutely sure you use a QUALITY Torque Wrench no matter which way you go. You must get the head back on evenly or you will have real problems!
Be careful when tightening the extended head bolts on the Pro-Design Coolhead. If you tighten them past the specs, you can snap a head bolt. Just the thought of this hurts my stomach!
AND BE SURE TO USE A QUALITY RACE GAS! Aviation Fuel is not good since it has petroleum distillates and glycol in it to prevent from freezing at high altitudes that airplanes reach. The FAA requires these additives for Aviation Fuel. Don't let anyone tell you differently! This stuff will just gum your engine and exhaust system up. If race gas is too expensive, mix it with a quality pump premium (92 Octane). You will then be at about the same price per gallon as Aviation Fuel, but have a much cleaner burning engine.
Good luck!
