Thank you

Engine cylinder head number. Also stamped in the rocker arm assembly area. Quick reference for the person building type 4 motors.

I am gonna say casting number, but check in underneath the valve cover there should be a visible number that would match that one.

What size engine is that?

I think when there is the blue stamping of part numbers on part numbers when there ususally isn't one on that part means it's part of an exchange program. The PET doesn't haver that exact part number, but the closest is for 021 101 061 which has another part number in the description, 022.101.372, "Cylinder Head exchanghe, with valves, D-Jetronic M W0 002 545 >> W0 129 581, cam follower protective lube, 31.7 mm 022.101.372 embedded" whatever that all means... 371 probably unlubricated version.

He can read
He can read what?
Now that we know we can all read (har, har, har)
What is the lay mans version of
PET, cylinder head exchange ( dealer or factory replAced?, modified?)
Lubricated, non lubricated, with valves?
It's apparent My cerebral cortex isn't as large as Richards is and am looking
For a little more explanation.
Thank you

PET is "Porsche Ersatz Teile Katalog" or "Porsche Parts Catalog".
http://www.porsche.com/all/media/pdf/originalparts/en/E_914_KATALOG.pdf
Factory exchange program is like when a service place would get a replacement engine or just the replacement head. You'd get a whole blank serial motor, one that had both bus and 914 oil fill options and the service department would stamp your original engine numbers on it. They might have replaced just the head if the owner smoked the valved during warranty, or possibly during the 80's or 90's and dealt with a place that used factory parts. Later repairs would have been more likely to use aftermarket parts as those original factory replacement parts became nla. I'd be all over factory exchange heads or whole motor if you could get those still.
The other stuff, "embedded" I'm not sure. Seems the replacement head came with a tube of lubricant for greasing up the lifters and pushrod ends. Also not really sure what is 37.1 mm, might be a reference number rather than a metric length?
The W numbers I think are engine numbers; if you had an original engine with US issue djet within that range, that's the replacement head you'd order. OP is 1 number off which seems to have been superseded in this version of the PET. With valves, just that there is a part number for the head and for the valves individually but also for this replacement package.

Thank you for the explanation Nathan.
I appreciate you taking the time to better "spell things out" for me.
Thanks again
