Nailhead Casting Numbers Updated
 

I have found a fairly reliable source for Nailhead head and block casting numbers. I have updated our list to reflect changes.

How accurate is this book? See Link.

I have that book and use it too. Some of the numbers are part numbers, but you might as well own one.

If you buy it through this link the site gets some support:

Intake casting numbers
 

I have a few more casting numbers of intake manifolds that I have:

1170616-3 1955 264cid
1165308 1954-early 1955 264 cid
1170624 late 1955-1956 264, 322 2 bbl
1170617 1956 322 4 bbl
1363782 1962 4 bbl
1185976 1964 4 bbl
1383782 1965 4 bbl

Thanks Airy Cat. That's what we need to compile a more complete list. I have added the numbers you have found. I would like to set up something where Buick owners can add info they know of.

head casting numbers
 

Having trouble accessing the nailhead numbers list. No authorization?
Saw an engine at an upcoming sale, and could read 11663491 on one of the heads. The pic is kinda fuzzy, so not sure about the first 6.

Need id of my block please
 

Casting # is 13327894...it is not listed but definitely a nailhead.
Can you tell me what year and cubic inch
Thank you,
Guy

All the casting numbers I have that are reasonably identified are listed.
You can tell which motor the intake will fit by measuring across the stud holes. The measurements are partway down this page:
