Default Ignition shield mounting

Before I jump into removing the bolts on the intake manifold to bolt up the ignition shield supports is there anything I should be aware of and during the installation of the bolts holding the ignition shield supports, Should I use some sort of sealer on the threads. Also looking in the manual for the torque limits on the bolts and I'm not 100% sure how much to torque up.
My vette is a 1970, small block 350/300hp stock manifold.
Thanks in advance for the info.

Yes you need thread sealer and torque the bolts to 35 if it is a cast iron intake, 25 if it is aluminum intake.

Thank you very much for the information. I wasnt able to start the job on installing the shield yesterday due to the honey do list but got that out of the way and will be able to install today.

35 ft-lbs on 1/4" trim bolts???? Sounds like a lot to me.

I believe we're talking about the rear manifold bolts that hold the ign. shielding supports in place.

If those are 3/8"-16's, 32-36 ft-lbs. is correct. [Thanks for clearing that up.]
