Camel Hump Head ID

Hey gents,

I have a set of 462 casting SBC heads with date codes L56 and K306. If I deciphered these correctly does that mean they were made in Dec 5, 1966 and Nov 30, 1966 respectively?

Also, is there any chance these came off or are the right head for the fuel injected Vette engine of the time?

Lastly, what is a ball park value on these heads?

Thanks.

Brent

To be honest with you, the camel backs have fallen to the wayside ever since the Vortec head has been released. There's no way to know what the heads came on as chevy did not put specific ID's on camel back heads. However if memory serves the FI Vettes had 2.02 intake and 1.60 exhaust valves factory standard, however, it's popular to have the 1.94 1.50 valve sizes bumped up to the larger valve size. It was some time ago I seen a pair on ebay some guy claimed came of a "DZ" 302 and the bid was over $700 and climbing, funny thing was the heads were 1.94 valve size which the DZ never came with not to mention the fact the heads were not stamped "DZ" at all. Whoever got those heads paid around $850 total for them then had to invest another $500 to get them in useable shape when they could have spent $600 on a set of Vortec heads ready to bolt on and been 30 horsepower over the camel backs.
The date codes show December 5th 1966 and
November 30th 1966 as you listed. As for what they worth, they are worth whatever someone is willing to give you for them. Your best bet is Ebay if you want to sell them.

Thanks Double. Yeah I am listing them on eBay now. They have been totally gone through top to bottom. Guess I will throw it up against the wall and see if it sticks. Thanks for the reply.

I agree with first post...

I can't believe some of the prices out there on ebay...I do buy a lot on ebay, but when I check on Craig's List for parts, I see camel humps going for under $300.00 bucks and they have been redone...I used them back in the 70's and ported them myself...worked good, but like the other gent said, the Vortec's are hard to beat and most will go to those, or the aftermarket...Unless, your one of those guys trying to restore...I have seen 461X heads selling for $1,500 a pair~! Crossram intakes from Mickey Thompson for $1,500 and the newest "possible scam" are the NEW knock off 1969 GM crossram? But they are not made by GM...My question is, since GM did so much R&D on the original, how close of a clone are they? Most of the crossrams within the aftermarket had no r&d, like the edelbrock that I have seen selling for that pie in the sky figure...I pity the young guy that buys it today, because all he is going to have is problems setting them up...
Good luck and may you find your pot of gold~!

I ran those "462" numbers but I need the first numbers since there were more than one "462" head made. For example there was 3890462 and 3891462 and about 4 others. It could be a '67 Z28 cylinder head on the fabled 302, or it could be a 327/300hp engine with 1.94/1.50 valves.

Even so I'm not sure why, some sites show a 3891462 casting but others do not and none of my books list it either. On the sites that do list it, it comes up the same as 3890462. The only other head that I see that ends in 462 is the 3767462 head for 62 - 67 327, but these don't have the camel hump marking.

It appears Chevy had 6 different heads that ended in 462. At least 2 of them were camel humps. Get the rest of the numbers and check this out: http://chevytech.info/3c10o12.html
