Have a pair of untouched “461” casting SBC heads, date coded 1964. They do not have accessory holes. They have 1.94/1.50 valves, haven’t been altered for performance use, just a good pair of cores. They came off of a running engine a few years back, but have been sitting for about 5 years and would probably need to be rebuilt. They are complete minus 1 intake valve and spring. Selling for $200 for the pair, cash only!
