Sleeper 103?

What do you guys think of the sleeper 103 kit from Zippers. Doesn't sound to bad,with a little head work it might not be bad for a mild build on the cheap?

Turn your "Sleepy" 96 inch engine into a "Sleeper" 103 incher!

Cylinders (supplied on an exchange basis) are precision bored and honed on torque plates from 3-3/4" to 3-7/8" and fitted with forged pistons. Red Shift cams and adjustable pushrods let the engine breathe for a substantial increase in usable torque and horsepower. A complete top end and cam change gasket set included.

Two versions are available. 517-300 is the best choice for lighter FX-style bikes (Dynas® and Softails®), includes flat-top pistons and Red Shift 577 cams. 517-301 includes dished (-11cc) pistons and Red Shift 575 cams for earlier torque delivery and lower temperatures in heavier Touring bike applications.

Biggest bang for the buck - only $1,029.95 with exchange cylinders!

Cylinder/piston kits available separately.

Expert installation of this product is available at Zipper's facility in Elkridge, Maryland. Transportation of your motorcycle to and from Zipper's can be arranged if desired. Please contact Zipper's Performance Products for details.

It's got better cams than the Harley kit comes with. I have used there kits on Sportsters an they do what they advertise.
It's good to think outside of the box!!!
