I have the specs at home in my Century service manual. It's funny how they add the 3800 II teardown specs to a car that didn't have that engine. Will post it and pics around 12:00 Eastern Time when I get home. There was teardown and order to tighten.

Should be if it has 3800 engine in the book. Century/Regal are same car but they don't have the same engine. Depending where you go they assume the Century has a 3800 II option. No 90 Degree V6 engine comes in a Century from the factory.

Well I got the job done on the intake only to test drive it and find a big leak coming from a hard plasting 90 degree elbow connected on the passanger side lower intake and sending coolant from the casting above the water pump.

When I was test driving I found that my heater was blowing cold air and the temp gate was reading hot because It had blown out all the coolant on the drive out of the driveway.

LOL where were you before the GM garage told me that it was that gaskets lol. I just bought those today from NAPA for $4bucks an change.

But now I have New Felpro upper and lower gaskets and valve cover gaskets and I cleaned the throttle body with carb cleaner while it was all apart.
