  • General Recommendations

    Wilkes Performance assumes no responsibility for damage if the end user builds an engine without properly verifying he has enough piston to valve clearance (depth and radial clearance both checked). It is recommended for a minimum depth of .080″ on the intake valve and .100″ on the exhaust with a radial clearance of .030″ minimum around the perimeter of each valve.  It is the customers responsibility to verify proper piston to valve clearance.
