Cylinder head ID

Can anyone give me any details about my heads? Inside the heads there are 2 numbers:

They appear to be factory 87 or newer centerbolt heads from as far as I can tell. They have a clock stamping and another stamp that is two parallel lines similar to the number 11. I believe my engine is a 87 or newer 350 block, and has supposedly been stroked. Any help whatsoever would be appreciated.

I couldn't find that number. The closest I could get was :

14096217...55-86...350..........Crate motor, 285hp/300hp, 64cc chambers,
.........................................72' or 90' center intake manifold bolt angles

F2861..... 1981 or 1991 ??

Re: Cylinder head ID

You're correct on the number. After cleaning it a little more the 3 became a 6. According to this website:
and two others that I've found, the heads are 90 or newer and flow 1.94/1.5. I can't read the block stamping, and don't feel like pulling the head to look for it, so I'll just let the engine remain a mystery for now.

Re: Cylinder head ID

You mean that you can't see the little deck pad that's right above the pass. side, top water pump bolt so you can post back the letters at the end of the VIN number string so we can decode it??
