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.
CNC Porting
On occasion a 100% CNC ported head might have casting areas left “as cast”.This is due to core shift and this in no way affects performance.
Disclaimer
Wilkes Performance assumes no responsibility for damage caused to engines from modifying bought castings. These products are now classified as racing products. They retain oem valve seats, oem casting material that was purchased by Wilkes Performance. This extra horsepower and added heat can cause casting failure. Wilkes Performance did not cause this from porting or valve jobbing the aftermarket casting. Any warranty is from the original casting manufacturer.
