When you finally get to the step of pulling the lower intake as pictured above in the first pic. The intake comes off FIRST,

MAKE SURE YOU MARK THE THE PUSHRODS THEY ARE DIFFERENT LENGTHS!!!!!!

then the pushrods SECOND and then the intake gasket itself.

Called one of my buddies that worked for GM for along time and he answered my question. Guess this thread is considered theropy sense I seem to be really talking to my self, hey the doctor said I should write down things rather than talk to myself

(really I am sane just silly).

and don't forget the rtv! also keep an eye on the rear cover gasket, sometimes they slip out just a little and create an oil leak( as my brother found out the hard way).

Thanks I'll keep that in mind. I did do that on a chrysler 3.3 in the vans and it was a pain.

Does anyone know if the intake bolts go into any water passages? They have a bunch of gunk on them but I can't tell if that is just gunk or teflon. Oh and does anyone know the torques specs. When I pulled the lower intake the bolts WERE JUST barely hand tight. Didn't take much to break them loose(maybe that is why it was leaking).

Don't know the torque specs, but I did want to remind you that everything should be retorqued after the first hundred miles or so.

NOT! Where did you hear to retorque a lower intake after 100 miles?

OEM would have had a non harding threadlock/sealer on them
That is not the way it left the factory, someone did a botched repair!
