FEL-PRO ES 72224 Engine Intake Manifold Bolt Set for Chevrolet K1500

These are high quality, fit great, sealed and worked great. They are heavy duty and performed there purpose.

Works great

Did the job, these are for the vortec intakes as they don’t get bolted down as tight.

I found and purchased these as an alternative to the more expensive ARP equivalent. Good amount of savings from another brand name that I trust enough to used their gaskets on the same application project of my 2000 GMC Jimmy SLT 4x4. Verify but as far as I know this will for same S series blazer 4.3s and similar year Jimmy 2 or 4 wheel drive all trim levels. Anyway, good idea to replace these when removing the lower intake as they are fairly torque sensitive so not a great idea to reuse the originals.

I used the bolts on a 1979 350 chevy engine that I put 1999 vortec heads on.The bolts have thread sealer on them. I’ve ran the motor just long enough to break it in. I haven’t noticed any water leak’s around the bolts.They are the proper size and length for the vortec manifold.

I purchased these to use after replacing my intake manifold gaskets on my 1998 Chevrolet C1500. It is recommend to change the bolts when removing the manifold. The new bolts come with the thredlock and are supposed to seal to avoid coolant leaks from the bolts that go into the coolant reservoirs. I purchased these bolts because i used the felpro gasket kit also. Felpro is a reputable brand and i honestly have not found gaskets that are built better. The reason i gave the bolts four stars instead of five is because they are made in China.

Work as they should.

Works well just what was needed for my Chevy Tahoe
