What is Cylinder Head From ?

[Martyn]

I recently acquired this head in a box of bits . The bore dia is 76mm so I think it's a 1600.
The markings on front are not 105 . The chain tensioner housing is different end with no removable hex head nut.
Hope someone out there can explain what it's from.

Early 1600 head. 105 sprint gt. You'll also notice the 2 bolts at front of cam cover missing. I think they improved them from around 1966 onwards with the 2 extra bolts to slow the oil leaks.

Thankyou for the info.
