OK, now the heads.
Here are the gaskets (LS9 version):
These are vacuum bagged so you'll need to be careful getting them out. Also, you'll need to pay particular attention to any 'leftover' packaging -- it does stick to it so inspect both sides and the openings...
Make sure to orient the gaskets to the front when installing them:
Also, you may need to remove the 'Made In Germany' tag too:
I decided to do the passenger's side as its a bit 'tricky' to installed:
Gasket on and oriented correctly:
On the Passenger's head, you'll need to put the 'coolant' plug in -- goes on the back upper side:
From my old head:
New head:
Metric Allen to remove/install with:
Installed (be sure to put Teflon tape/paste on it):
Here is the porting on the GPI heads:
Exhaust:
Intake:
As good practice, ALWAY clean again (cleaned the heads to be sure!):
Verify you have the coolant rivet installed in the back of each head:
Now the head bolts:
Ready to install right out of the bag!
Heads cleaned and ready to install!:
Torqued!
I did make sure NOTHING was in the way of the gasket or head and that it was clear of obstructions -- hate to install and find a wire in the way!
Now, the torque sequence was this:
bolts 1-10 were in 3 steps
11-15 (the smaller ones) done in 1 step after 1-10 (according to the manual)
bolts 1-10 were:
22 ft. lbs first
90 degrees second
70 degrees third
here is the sequence:
Specs:
Driver's side:
Gasket -- oriented correctly:
Driver's Head installed!:
I had to be He-Man to torque the Drivers side while the engine is in the car -- wow!
Time for a break -- I'm tired ;o)
