Stamped Valve Covers
These CHEVROLET Bowtie valve covers are made of heavygauge steel, 20% thicker than typical aftermarket valve covers,
greatly reducing the likelihood of leakage around the valve
cover flange area caused by fasteners being over-torqued. The
chrome plating meets GM quality specifications. All valve covers bear the powerful Bowtie and CHEVROLET Emblems.
Black crinkle valve covers, with their distinctive look and boldly striking Bowtie and CHEVROLET Emblems, inlaid with classic
Chevrolet red, are CED painted for long-term corrosion resistance, and then black crinkle painted on the outer surface.
Stamped valve covers are offered in either tall or production
height (short). Oil restricting baffles are offered in many valve
covers for those who wish to maintain the PCV hookup. All
valve covers are sold in pairs, equipped with air breather and
PCV grommets, unless specified otherwise. Technical Note:
Production height Chevy small-block valve covers and valve
covers with baffles will not clear most stud girdle applications.
Chevy small-block or S/B refers to 1958-1986 engines,
unless otherwise specified. B/B refers to big block engines.
