Anyone know the specs on this W2 head

[Rocket]

My friend has aset of W2 heads that have been sitting on the shelf for 10 years. Part number is P4876336. It is a closed chamber head. Anyone know if it is a 59 degree or 48 degree tappet head and what the valve angle is - 15 degree or 18 degree?

I can't seem to find much information on the specifications.

Thanks
