Re: 1997 GM 3.8L Factory Manual specs wrong?

It may be a typographical error, or it may be that the upgraded gaskets have a different specification. I've used the FelPro MS98014T and complete Dorman 615-180 upper kit without failure. The lowers are torqued to 150 in/lb in four rounds of following the sequence, with threads cleaned/chased and PST (Loctite 592 or Permatex 565) sealant applied to prevent thread wicking on the LIM bolts. The uppers are torqued to 85 in/lb in four rounds through the sequence.
