These Cobra valve covers are similar to those used on the 1965 and early 1966 Shelby GT350’s but are engineered for use with more modern high RPM valve train components. They fit all 260-289-302 and 351 Windsor engines. They are taller than the original type, with a flat top to clear the roller rockers and the poly-locks required for today’s high RPM usage. Cast aluminum with highlighted fins.
