Heads off of 73 455. Recently removed from block that has been in my garage for 10 years or so, and it seems it would have been better to leave it sit outside. Block was junk, but the heads are interesting, but also a little rusty. Intake valves measure 2.12 and exhaust measures 1.75. Casting number 1241860 is showing 176 cc intake, 134 cc exhaust. I'd rather not ship as they are heavy, but would like to get $200.00 plus freight?
