Foot Notes (far right column)
1 - Most Wiseco Pistons have offset pins. (Pins must be offset, same as OEM, for quietest operation).
2 - Due to compression height that may protrude above the deck, it is recommended that a
1.00mm thick head gasket is used.
3 - Optional pin upgrade available.

1. Most Wiseco pistons have offset pins. Pins must be offset same as o.e. for quitest operation-pin offset will be opposite of direction of engine rotation
* Always run at least .030 piston to head clearance including gasket thickness.

* Always check piston to valve clearance - If using VTEC or like mechanisms-check w/ longer duration higher lift lobe.
* Some pistons are listed with a range of compression ratio's. The low number is determined w/ an un-cut deck and the higher number is determined w/ .030 piston to cylinder head clearance.
