First.... before bumping your post... give it at least 24 hrs. Your first post is at mid-night... and your second post is at 9am on Sunday. People go out, on Sat night, and sleep in on Sunday... and most people who are qualified to give you the answer you need... aren't on 24/7.
Second... if you are going to work on an 951 engine... you need the manual. That head has studs, and bolts, and since it has a real head gasket... there is a torque sequence that needs to be followed. Also... the "Carb" and the "Di" version use different torques.
You have carbs... so, start with the bolts, go in a criss-cross patternt and torque to 133 Lb/in. Then do the nuts. Then... go back, and re-torque to 25 Lb/ft.
I recommend using copper coat on the head gasket.
If the proper torquing sequence isn't followed, you will warp the head, and have head sealing issues.
