yes i have a set of fe heads man told me they were 63 406? the casting # is C3AE-6090C did i buy 406 heads jack?

According to my reference book, your heads are : late 1963 406-6v, w/ spring seat cups combustion chamber volume in c.c. is 56.4-61.0, valve sizes should be 2.022-2.037" intake and 1.645-1.660 exhaust. I hope this info helps! Dean

Hi Jack, Your heads are mid 63 "high compression" heads; 406 heads if equipped with 1.66 exhaust valves and machined valve spring seats; small combustion chamber like the C1AE-6090-A head. Low riser.
By the way, I enjoy your stories and pictures very much, thanks for posting!

thanks im looking for more pictures have some more by the way what you thonk heads are worth??4233197814

no cups, probably an entirely different head with the same number.

As noted above, if it has spring cups under the valve springs and big valves it is a 406 head but if it does not have the cups and has small valves it is a 390 high compression head. Either way they are better than a standard C1AE or C4AE head because they do have a smaller chamber. Hawkrod
