77TARGA

Since the birth of my son, 13 months ago, my other baby (1980 911sc euro) has been sitting in my garage with a terrible oil leak, and I finally told myself that I need to take the time and fix it. My first question is what size are the allen head bolts that holds the exhaust manifold in place (the one you need to go through the heat exchanger to access), I think it is around 8mm but I need a driver to fit on a ratchet to be sure, and I don't want to buy tools I don't need.

The second and most depressing question... I think I saw a broken head stud floating around under the valve cover, I definately can not afford a rebuild, so what kind of price could I get out of a 1980 euro sc roller with a good 915 trans, good body (cheap paint job) and a motor that needs an overhauling?

Porsche sc

8mm , is the correct size!
