*This is a performance part and as such requires setup during installation like, setting ring gap, chamfering ports, squish check, proper jetting, timing, break in periods, and often other components to be replaced to become reliable. Manufacturers label these as race parts and do not warranty race parts except when a part is defective before installation.*
