<VV> Retorquing Heads

[Frank DuVal]

We retorque lower head studs when doing o-rings, and at times I also 
check the upper studs. Since you are resealing, you will be doing the 
lowers anyway, so change the socket and check the uppers while you are 
there. Go for the lower torque value on the uppers, as there is no 
reason to disturb the rusty threads if they are not loose. Of course one 
may argue that the rusty nuts will affect the torque reading of the 
upper studs, so you are really just checking to see if things are really 
loose! And don't cause more headaches by loosening the upper nuts first. 
Only do that when removing the heads.

Don't forget to deflash the heads while it is open. Remove mouse nests, etc.

I'm debating (myself) on  re torqueing  the heads while I can get to all of the bolts and nuts. This is a 48K mile motor and runs great other some valve rocker arm lash noise that I will adjust out after the reseal. What do people with experience think?   Thanks, David in OKC
