Good price, good part
Second time using these, worked well the first time too. Also one of the cheaper sets I could find.Note: these have a 'sealant' on the shaft where it meets the flange. This replaces the need to have the rubber washer which factory version included however the sealant wasn't very thick. I used a dab of RTV around the joint surface to seal just in case.

Replacement bolts
These bolts replaced the factory bolts perfectly. They included the tread lock material already installed on the bolts, no need to get out the Loctite. On the Buick 3.4 liter engine the bolts are torque and angular rotation bolts that are only supposed to be used once. The base half of the intake manifold must be torqued to yield and these were perfect for that. The upper bolts you probably could do without since you really can't torque the end bolts, it is not possible the way the manifold is designed so you could probably get away without using half of these bolts. The fit and length were a perfect match for the original equipment bolts.

GM 3100 V6 replacement intake bolts
Excellent quality--needed these whilst replacing lower intake gaskets on my 94 3100 GM v6---Olds Ciera. 10K miles later, still holding my intake down!

Also worked on my 1998 3.1 engine
After reading numerous reviews for the Fel-Pro Es72225 Intake Manifold Bolt Set and the concerns about the short bolts being too short I took a look at this set. After all the 3.1 and 3.4 are the same engine family. Even though the item description and product packaging do not list my 1998 Chevrolet Malibu 3.1 as an application for this bolt set, once I got the intake off and compared the old bolts to this set they are identical in size, and worked perfectly on installation.

Great
Good bolts, I just wish they came in the head gasket kit.

Work perfect.
These worked perfectly for my 3100 on my Lumina. It's stressful when doing a big project like the lower intake gaskets on these motors and I was very happy when these worked just like stock bolts.

Correct bolts even thought amazon says no
I have 2000 impala with the 3.4L. These bolts were the perfect length and fit to the pen bolts. Amazon says these do not fit my vehicle but I can tell you they did fit mine.
