Bring'em over when you come over Craig.... I'll grab'em!

what difference do thay make?

Hey VWkid...
More efficient valve train with little to no thrust load on the cam bearings... Which equates to higher efficiency at the cam lobe to cam interface and more hp.... Plus they sound good!

There's basically no axial thrust on the bearings because of the straight cut design, whereas helical type gears tend to force eachother axially because of the screw action made from their spiral shape. Straight cut gears (Spur type) have a smaller tooth contact area, (One tooth in contact at a time) thus reducing the area which takes the load. Because of this there is a clicking sound made at low speeds, but because the cam and crank are rotating relatively fast this is heard as a whirring sound. Helical gears spread the load over a larger area and over at least two teeth at a time, which means the rotation is smoother. Gearboxes commonly use spur type for first and reverse, and helical for the rest. You may be thinking spur type are weaker, but they are usually made stronger in the first place. All this means you would have a strong gear which causes less wear to the bearings, giving better performance.
And that's the way the cookie crumbles.

I think I may have gone a little overboard.

LOL..... Or maybe my description was little simplistic?

Maybe yours was a little more appropriate.
