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. D - Weight reduction possible.

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.
