They could have been included on 327, 350 and 67 302s. Horse power ratings varied from 275, 295, 300 and 350 in the corvette and chevy II applications. they could have 194 or 202 intake valve sizes depending on the application. If they were late 1966 heads, then they were 62cc chambers. If early 67, then 63.3cc. They are similar to the 461 heads in design.
