On the stock manif. bolts, what does gm put on them? It kind of looks like lock tite but they wouldnt do that on aluminum heads. Is it some kind of anti cease? Do i need to put some more on the bolts when reinstalling them?? Please help!
Thanks,
Derek

 

I never have put anything on them except anti sieze.

 

Yeah anti seize on anything with high temp applications or dissimilar metals.
O2 sensors, header bolts, spark plugs, exhaust bolts.
