I bored my cylinder out to a 426. I am running at stock compression wiseco piston. Everything else is currently stock. Do I need to change jets to make up for the larger piston? What sizes will I need? Also, will I need to adjust the valves differently than stock? If so, what settings? Thanks for any help you may offer.

it probably wouldn't hurt to go with a keihin 150 mainjet. if your running the stock cam, you use the stock valve specs.
