The HEI mod is not necessarily going to increase your speed. The main reason for performing this mod is to avoid the high cost of replacing the ignitor which is $100+. If you want to increase your speed you need to increase the gear ratio and the easiest way to do this is to run bigger tires.
The shorter belt for your cart is the DAYCO HP3004 however you should be warned that some people have found that with a tired driven clutch the belt will cause it to open too far and hit the rivets in the center.
There is no magic bullet solution to increasing the speed of your cart other than ensuring the engine is as good as it can be. The compression needs to be 120+ psi, the crankshaft seals need to be sound and the carburetor needs to be clean.
