I had to do my moms head gasket on her Pontiac Gran Scam GT also.

Here are some pictures of how some stuff went back on. Let me know. I may be able to help. I took a bunch of pictures so i can remember how things went back on. Which i had to use a bunch of times. Brackets/wire harnesses etc.

Whoops.. Can't attach a .zip file. If you need them let me know i can shoot them over by email.

 

i have replaced many intake gaskets on 3.4s i just could not remember the torque specs. Im in larame wy and no one in town could look the specs up for me. Thanks i really appreciate it. i need to get the car done today it is supposed to start snowing the beginning of this week and i still have to do some work on my truck too.

 

Love your avator, Dan. I feel the same way about my beloved Broncos...

 

Buffalo Sabres are not doing any better.. Bad year for sports this year. I am bummed.
