Can't find that number, I looked thru:
Ziggy's Chevy parts finder
SBC small block interchange manual (by Lewis)
Chevy Parts Interchange (by CarTech)
Chevy Performance (by SA Design)
And MorTech Web Site

Sorry I can't help,
The closes number I could find would be 3947041, just wondering if these numbers where easily readable.

I got the numbers over the phone from the seller and was wondering the same thing.

I tried a few variations of that number and still no dice.

Closest I come up with according to all my books is that they may have trouble making out the numbers on those heads. Sounds like a set of 041's which would be GOOD. See if you can get any other information from the seller, such as the shape of the casting marking of the front of the head and possibly have them look at the number again with a pair of glasses on. If that engine appears to have never been apart ask them to give you the code off the front of the block (usually 2 to three letters at the end of the number stamped into the flat surface on the block in front of the pass. side cylinder head). This code will let you know what vehicle that engine came in, what it was equipped with, and the HP rating of it. If you don't have a book that gives you that info, just post the code here and I'll be happy to give you the info. Hope this helps!
