Well, it seems I'm still searching for a 1972 318 head for my 28' express, single. The mechanic says, as best he can tell, the casting # is 2843875-21. EWRice, you mentioned that with the casting number you would check to see if you might have one compatible, if you would do this I would be grateful. I've been fighting this all summer and now just trying to get it running in order to Winterize.
Regards to all,
Rockxx

They list the marine 318 head on the website but it seems a little vague about whether or not they have it in stock.

Might the number be 2843675? That is the generic 68-74 318 head. I will check my stock tonight. How many do you need?

Thanks,

The only 2843675 head I have is in my scrap pile. Don't know why, but it has been blasted so I assume it is cracked. Your head is a large chamber head. The only good heads I have are small chamber. However, I compared your head to some others in my scrap pile. 4027593 (77-84 318) has the same chamber design and size, as well as valve size. Being a later design, you are gauranteed hardened exhaust seats and rotators on the springs, both a plus. The only difference I see is that some of these heads were drilled for A.I.R. ports. Other than that, they are the same as what you need. Chrysler did not make a special marine head, so any head with the correct chamber will work. PM me if you need more specific info and I will give you my number.
