1968 help
I need a head for my 1968 C10, trying to stay as close to original as I can with this tuck tat belonged to my grandpa. Casting is 3921968.
250 I6, three on the tree. Thanks, Joey

Re: 1968 help
Also, what are my options for cylinder heads if I cannot find a 3895052 or 3927763?

Re: 1968 help
All the L6 series engines use the same head,
Just don't get a later head with integrated manifold.

Re: 1968 help
OP, what makes you think that the head you have can't just have a valve job?

Re: 1968 help
Steveedee makes a good point. If you do have your head in for a valve job, ask the machinist to use Stellite valve seats. The originals were made to run with TetraEthylLead additive in the gas. That stuff's been illegal in Cal for 25 years.
Stellites are better equipped to handle the goofy gas we get nowdays. If you do find another L6 Head, it will need a valve job anyway, if not other machining operations.
