Premium Black crinkle hold down clamps with distinctive look and boldly striking Bowtie Emblems, inlaid with classic Chevrolet red, are CED painted for long-term corrosion resistance, and then black crinkle painted on the outer surface. By spreading the load over a wider area, this clamp minimizes distortion of the valve cover flanges, thereby decreasing the possibility of oil leakage. Fits Chevrolet small-block V8 and V6/90 engines through 1986. 4 per package.
