Thanks Mike! The 400 is the small valve XV code 400 that had the 10.0 to 1 (80 cc) small valve #16 heads. It was rated 330 hp/430 lb-ft torque and available in the non-GTO A-bodies and Catalina/Executive B-body models. With a minimal cut to ensure they were flat, the measured 78 cc's, otherwise totally stock (190 cfm intake/145 cfm exhaust flow). The calculated static compression ratio is 9.94 to 1. Have to run true log exhaust manifolds, not RA's.
