Cylinder Head Casting Numbers

[jthornburg]

I have a puzzle. I purchased a 1970 V-197 Glastron with a V-6 Buick motor 155HP 225 CID not knowing the cylinder head starboard side was cracked. After further research I have been told that I need to match the casting numbers exactly. Well, I finally found a used head but the fifth number is five numbers different from mine.<br /><br />Does anyone know what these numbers designate and if I would be safe purchasing this head? Here are the specifics to this motor:<br /><br />SN: J0104615<br />Model: HUTM-69M<br />Cylinder #: B-1376346<br /><br />Any help is greatly appreciated!!

If you have the head off, take it to any automotive machine shop. They can identify it and find you a good core. Of course they would want to do a valve job for you as well.

DHPMARINE:<br /><br />After speaking with many sales reps for salvaged parts they told me to make sure I have the exact casting number. How do I ask Iboats if I can e mail you at the other address? Thanks for your help!!

Boomyal;<br /><br />I did take it to a cylinder head shop and he had no idea. He narrowed it down to a Buick motor but that was all he could do. Thanks anyway!
