Decoding 350ci Head ID numbers/castings
Does anyone have information regarding the casting and ID numbers found on the heads where the rockers are?
I just did valve cover gaskets this past weekend and wondered if these numbers would be able to tell me anything about the heads, without actually pulling the head off itself!
This is what the markings are:
W NH 1-037
This is the driverside head, both heads have identical markings (thankfully.) I did confirm whomever built the engine before I owned it put in a roller valvetrain. I just don't know enough yet about Chevy engine ID castings.
Thanks for your help!
