You can have your cams degreed, that's stock cams with adjustable sprockets or...go with bigger cams which increase the duration of the opening and closing of your valves and they are degreed as well. Cam degreeing is not hard but you have to be exact with everything or the entire process can get messed up and worse...valve bending mess.

WHAT IS DEGREEING IN YOUR CAMSHAFT?
Degreeing in your camshaft means synchronizing the camshaft's position with the crankshaft. A few degrees of misalignment can affect the engine's operation dramatically. If there were no manufacturing tolerances, you would only need to line up the marks on the timing chain sprockets and the cam would be degreed, but with a group of components (the camshaft, crankshaft, timing chain, and sprockets) all with their own standards and tolerances that when installed, can stack up against you. You can never be sure that the cam is in its correct position until you degree it in. For best performance, you should degree in all performance camshafts.
The basic tools required are a degree wheel, a stable pointer that can be mounted to the engine, a dial indicator with at least one inch of travel in .001" increments, a stand that mounts it to the engine, and a positive stop device to locate TDC.
Web-Cam offers a complete cam degreeing kit, see below for part number information or call for more information.
If you change your timing belt or chain, chain tensioner, cut your head, or deck your block, you must degree in your cams.
