3.1 Coat the cylinder head bolt threads? 3.1 Head Gasket 3100 Cylinder Head Torque

[97oldscutlas]

Just one more question before i go back together

 

***Do I need to Coat the cylinder head bolt threads using GM P/N(NNN) NNN-NNNNsealer or an equivalent???

Is this just red or blue Loctite? Do you guys recommend using or going on dry?

i guess alittle* doesn't hurt regardless..

I use black permatex and have done dozen. Never had one single issue.

how much do you use?

do you coat the top or bottom?

[19Cutlass94]

I wouldn't use permatex IMHO. I've used a little oil on the threads, this will help you get a more even torque across the head. But you don't need to seal them with anything.

those were my thoughts as well. that's why i found the Revised TSB questionable..

Just a dab around the middle and roll it about a half inch, I to this to all the bolts on the LIM also. Just my preference. And since those cars are still driving, guess it worked out.
