I have E heads on my 66 and also on my spare engine. They have been done for years and hate to take them off as they work.
Put a 455 together for a friend and used the SM heads. Light port work, hyd cam, factory HO intake. Car runs good but is just a driver. Car is a 73 SD bird and his original heads were cracked.
I have a set when for when I retire my car back to street duty hopefully within the next year or so (depending if I can find another 65-67 body to build for a racecar).
