I have a set of heads...the castings under the valve covers are:
6f26
the other is
6f30
I guess those are just the date codes
Both are also stamped WC P Thats all that I can see that is stamped on these things....I dont want to take them off to look underneath them- or am i going to have to?
What heads are these? I have been researching and i just cnat find them.
