413 Head casting number

[Inspector71]

The 413 heads are pretty grungy so I flipped one over. The casting number reads: 2406518-2. Is that a run of the mill big block head?

Clean it again and make sure it doesn't read 2406516...the numbers are cast in. Also check the port sizes as well as the vlave sizes.

Will do

It is actually pretty clean on the underside. The numbers are kind of hard to read with my eyes but I'm going down to give it another look. Be back after while. Hey, thanks for answering as I am confused as to what I have.

I wish I knew how to post pictures but I'm not sure that would help. The problem is, one one head, there is a tiny rounded "bur" where the belly of the six would curve up and around. The other head is worse. If the last number was a six, it has a diaganol line coming up from the belly of the six to make it look like an 8. It could go either way but my guess is it is probably a 6. I'm going to try and get some other, and much better, Mopar eyes on these numbers and clean the top of the head one more time. One head has good numbers in the top and the other those little pad numbers. Might be tomorrow but I'll let you know and thanks for the help.

Thats why I asked that you check the ports. 518's would be max wedge heads but the 6's and 8's are hard to tell apart. If the ports looks standard then you would have 516's if they look big and abnormally higher they would be 518's.

Do they have heat crossovers? If they do they are just a big block head, also do they have 4 or 6 valve cover bolts? 6 bolts are 64 and later!

Well I guess its a six

I cleaned off the top part and it appears to end in a 516-8 and it has six holes for the valve cover. But even the six on top has a slight deformity to it. The first six looks like a perfect six but all the last 6's are unclear. My guess is that whoever stamped these heads back in 64, knew I would be looking them over in 2012 and wanted me to think for a moment they were 426 Max Wedge heads. I sure was hoping so. I don't need them myself but was hoping they were so valuable I could trade them for a 62-64 Fury shell or a Dodge shell, same years. Oh well, I've learned a lot from you all and I appreciate it.
I was wondering, can I use after market Max Wedge heads (I see them in year One)? They have a 6 barrel carb intake for the Max Wedge. Might be fun.
