Look closely at them, I had to match mine up. Look at the machine pattern, and you will see where they match the block.

Default Caps

This is a critical area, If you are not Absolutely sure of their sequence then you might have to let a machine shop install them then do a align hone of the caps. Its better to pay that little extra now or you will wish you did..

Mine are numbered on the caps from the factory....2,3 and 4 are numbered on mine. Look really close and you should be able to see the 2,3 and 4.
