The collective knowledge plugged into this server is always impressive. Thanks to all for the "heads" up! To err is human and the great majority of you pluggers do forgive the unintentional and well-meaning errors. I assume the added bolts were to reduce oil leaking from under the valve covers. Reduced bolts appears to be a typical automotive mfr's cost saving move. Two bolts at two cents each times 500,000 heads= $10,000.

Oops! Sorry, begging forgiveness! Brain malfunction. The J had 4 bolt valve covers which was the last year for 4 bolt covers. They have the "ears" on each end of the valve covers but are not drilled. The heads do not have the "extensions" for the other two studs on the lower front and rear. This per George Riehl as stated in a 2009 email. The K started with 6 bolt covers: I assume the ram K did as well then.

Group I'm looking at a 300J engine. I need to know the # for the correct 300J heads. Anyone have that # reasonably handy? I did check the website first, but didn't find head #s listed. Did I miss a page?
