911SC Cylinder head torque

[natman]

Hello,
Trying to find the correct torque for the cylinder heads on a 79SC. I replaced the bottom studs with epoxy coated dilivar stud (a long time ago) and the original (dilivar/steel???) on top.
The Porsche spec book is showing a value of 24 lbs. That same value is listed in a Haynes book. In Bruce Anderson's performance book he also mentions 24 lbs for steel studs and 29 lbs for Dilivar.
My question is at what torque should the studs be. I thought in 79 that the 911 had Dilivar studs. I don't want to use different torque settings for upper and lower. Just doing the top end with 9.5 JE's and WebCams.
Any input, comments would be appreciated.

Dilivar was used from 78-82 1/2. Then they went to the coated dilivar. My spec book is 78-81 and shows the 33Nm which is 24.3ft lbs. If Bruce says 29 I would find the correct torque for a late 83SC before settling on 24. I put Raceware in and they state 25. I can check the factory manual later tonight and update if there is a difference in the late 83s w/ dilivar.

I got the dilivar info from this website.

Thanks for the info. I'll see if I can find the torque for the later SC.
