Correct tightening for the black saft bolt?

[CafeDragsterEFE]

Hello,

 

I have done new threads for the valve coiver bolts and I can´t find any info for the tightening for these black saft bolts. Could someone help me out?

Are you talking about the cam cap bolts? If so, it’s 6.0 to 8.5 ft. lbs. 

Or, the cyl. head cover bolts?

6.5 to 7.0 ft. lbs

In other units the cam cap bolts should be tightened to 8-12Nm And since those aren't original bolts I would check they are at least 10.9 strength.

Edit: Almost missed this was oilcooled section. Numbers are for the EFE engine which seems to be in the picture if I'm not mistaken...
