HI, I'm back. The following are the codes from the '64 HR 427:

Block : C3AE 6016-H
Heads: C3AE 6090 K
Manifold C4AE- 9425 G
Crank C3AE

The seller swears up and down that it's a 1964 high-rise engine and not a 1963. Can C3 mean 1964? I know 1963 parts still get sold in 1964, but aren't the C4 HR heads better than the C3 heads? Thank you.
