hello all, just got 1 of my cars I recently purchased home today. under all the junk on the cars floor was a cylinder head [only one dang it] casting number 2406516-8. I looked it up and it came back as a 361/383/413/426 [64-67] 2.08 1.65. can anyone fill me in on any details on this head? it also had 04196 cast on it. thanks in advance Gguy PS im a small block guy and now nothing about this particular head [Maybe the other one will be in the other car when it comes tomorrow]

Early closed chamber head. They have their uses. You can put hardened seats in them and larger exhaust valves.

What all else do you need to know? They predated the 915/906 heads, 2.08/1.60 (not 1.65 unless you measured them and someone before you put them there), have earlier style, less desirable intake runners...you can put the same size valves in them that you can with any other BBM head. They'll work on any of the engines plus 440s as listed above...they do not have hardened seats.
According to the little bit of literature I've read on them, the chambers were supposed to be around 75cc, but typically measure out closer to or over 80cc, intake and exhaust runners, I don't have info for--but I bet there's a member on here that does. If you haven't figured out how to use the search function yet, search in here for "516 heads"
They're good for a basic rebuild if you have no other option, but for power production pretty much any other later model head will provide better performance capacity. I hope that's a little more helpful

It's an old head. It will probably require more work than is cost effective to get it in good shape. It at least needs hardened exhaust seats. If you do that, you might as well upgrade to the 1.74 exhaust valve. It probably needs guides. Mild port work would be a big plus. By the time you do all that you could have bought a new aluminum head.
not very good to come on here ask for help, get a good answer and then ***** about it. Maybe take that link to Moparts and hang out over there.

RustyRatrrod youre answer was exactly what I was looking for. thank you. im a newbie on engine stuff and especially big block stuff and have been trying to educate myself as much as possible. the above answer was the only one I got in two days and tells me absolutely nothing to help me learn. I had no idea if I should of asked the question in a different forum or not. I kind of thought this was a site where there were many experts and car lovers wanting to share and grow their passion and knowledge for Mopars but sadly I am finding an awful lot of folks who can barely contain their contempt for those less knowledgeable than themselves. they seem to only be on here to dump on those who would dare to ask a question that obviously anybody should know the answer to and to lord their knowledge over us dumbasses.
My attitude is like this......regardless what some MAY think. "I" do not consider myself more knowledgeable than anyone. We all know things that others do not. So it all evens out. Sometimes, on the internet, tone is not very evident. Probably over 95% of what I post when I give an answer like I did here......talkin about the Moparts comment.....is just poking fun, yet it often does not come through that way. People who know me in person, know my sense of humor. I try not to get serious very often. We have enough of that crap.
I guess the best way to find out what you are after is ask what power level are you looking for? That in and of itself will pretty much answer what you need for heads.

guitar guy, RRR is actually one of the guys which you speak...he's plenty knowledgeable--ask him a more vectored question, and be prepared to receive plenty of good info, but your first response was just snarky enough that his reply was perfectly reasonable IMO. He doesn't mince words much...better that way...
They had to increase the flow of the bb head after 67 because with the launch of the 340 in 68, if they didn't improve the head flow, the 340 would have been better than the 383...
That's why the output on the 383 jumped 5-10 horsepower after 68...
Some people like to use the pre 67 heads with the closed chamber to increase their compression.

That Cylinder Head is nothing special.
Just an early 'basic' Big Block Cylinder head. It can be utilized on any 1963 thru 1967
361/383 Mopar Engine. Both 4-Barrel and 2-Barrel.
Also the 1964 and 1965 ~ 426-S 'Street Wedge'.
And the 1966 and 1967 ~ 440/350 HP 'Big-Body Mopar Cars'
Intake ....... 2.08"
Exhaust .... 1.60"
Combustion Chamber ..... Minimum {73.5 CC} ~ Factory {78.0 CC}

I told you three out of about four things you need to know about that head. Just google chrysler closed chamber head. There are only a couple. I answered how I did because you made it sound like you struck gold. Just search these threds for a bunch of stuff about them. If you go deep enough you will be immersed in combustion chamber design, compression, flame travel, etc. Also the one benefit that you may be able to take advantage of, which no one has mentioned for good reason...quench.
All this stuff about the 516 head is true. Small exhaust valve, smaller ports, blah blah blah......BUT, ask IQ52 what heads his dad used to break records at Bonneville back in the day. You might be surprised.
The bottom line is, you can make any big block head WORK.

I have a set that worked well on a 383. I will improve them a bit, and give them another shot on a bored 440. Just another crazy scheme of mine. Some work, some don't.
Any 516 head that comes into my shop goes straight to the scrap bin. I don't bother spending any time on them. It is a super old design that just doesn't work that well. Not to mention it is easy to hit water if you do try to do much porting on them.

So..in conclusion, these heads work just as good on the salt flats as on the scrap pile.
Any head made after the 516 is a better head, except for the 250, which is in my opinion a 516 with a big combustion chamber. But, if all you have is the 516, you go with what you have. Now days I too throw them on the scrap pile.
Except for this one time............
Post #44 is what happened when we switched from stock 906 to ported 516 heads. Included in the same post are the flow figures for those ported 516 heads.

Partially correct,
The reason Mopar went to the 'Open Chamber' Cylinder Head in 1968 for the
Big Block > was to reduce emission's at low RPM's to meet EPA Guidelines.
Also, the 1968 383 had an improved design in the Cast iron Intake Manifold, and better Carburetor with the Carter AVS {630 CFM}.
thank you guys excellent stuff here. appoligies for any snarkiness that may have come through as it was not intended on my part. yes I was hoping I had struck gold as we all do. I would gladly give this head to anyone here that has a need for it, for the cost of the ride as I have no need for it, but someone else may thank you all Ray.

So the car you bought didn't have a mate to that head sitting elsewhere in it? Might have better luck ridding yourself of a pair than a single.
