Notes:

#1 Most Wiseco pistons have offset pins. Pins must be offset the same as o.e. for quietest operation - Pin offset will be opposite of direction of engine rotation.
#3 Non-coated, not supplied with rings.
#4 This piston made w/stock compression height, which is very close to cylinder head. Use Cometic thick gasket if decking block.
Notes: that apply to all Part #'s:
*
Some pistons are listed with a range of compression ratio's. The low number is determined w/an un-cut deck and the high number is determined w/.030 piston to cylinder head clearance.
* Always check pistons to valve clearance - If using VTEC or like mechanisms- check w/longer duration higher lift lobe.
* Always run at least .030 piston to head clearance including gasket thickness.
* If piston appears to be different than expected, please do not hesitate to call Wiseco at 800-321-1364 to verify proper installation specifications.
