Hello all,

Can someone please tell me what the casting numbers are for cylinder heads on a 1955 331 ?

I have read online that the 1955 heads are a good upgrade for my 52 engine. My engine has bad heads now so I'm looking at upgrading with the replacement.

I have searched online a lot but can not find the casting numbers for 55 heads listed.

Thank you

Bob Kielar

Is this the number you are looking for? The picture is from a spare set of 55 331 heads I have.

I downloaded the page from the MidCentury Cadillac site.  Great info.
