Head replacement?

[v-4-6-8]

94 Metro XFI 3cyl 1.0L To replace cyl.head do I have to remove intake manifold & TB? also anyone know the torque angle degree setting,after new headbolts are torqued to specs.

If you have a spare intake and exhaust... no. Considering every engine head known to man has the intake manifold and exhaust manifold attached to it.. Yes, i'd remove them.. The new head will work better with them than without them.. Torque angle degree? Did someone feed you some wrong terminology? I've built many-a-motor, and have never heard that even said. Are you perhaps speaking of the ignition timing, or how to properly time the timing belt?

In referance to torque angle-Google Federal-Mogul+Clamping force

On some cars it's easier to leave the manifolds attached to the head while you remove the head from the car. N/A VW diesels being one. Dunno about Metros though.

Many head bolts are stretch bolts or TTY Torque To Yeild. After torqing them, you turn an additional 90 degrees or more to reach the final clamping force.
