Hello!

I wonder what casting numbers 1956 cylinder heads has.
I know that there is early castings that's prone to crack and later redesigned castings that doesn't crack so easily.

Please can somebody help me with the casting numbers of the early and later 1956 cylinder heads?

Thanks in advance!

David,

If you checked the first link that post has a lengthy details regarding the ’56 heads which Clay (aka lexi) has done an extensive research on them.

There are a few threads indicating the early ’56 casting were Left - 1465406-7 Right - 1462983-4 (still inconclusive data on the 1462983-4) while other thread shows the L and R having the same casting 1465406.
