There is a good chance you will need a tune after you do the swap, you may be running lean due to all the extra air going in, and the new timing of the cam. As long as you match up the Timing chains with eachother and the crank, all should go well.

 

the cams i am looking at buy don't have the gears on them so will the gear off of my nonpi cam fit on the pi cams and do the cams and gears have notches or keys or something so that they are put on in the correct postions

 

someone please help me out on this one
