RF-2C5EC064-AF is the casting number for the heads but all the casting numbers posted in the website are C5AE, C5AE-B, C5AE-F, C5AE-6090F, C5AE-6090F, now which one is the number for my heads?

Edgar,
The numbers that you found are all 1965 casting numbers. The number that you listed for your head is a 2003-2004 head. The classifcation guide shows the piston .008" in the hole and a 17cc dish in it. The head number you gave is for the 390 hp supercharged engine.
thanks, Roland
