Worked great on the intake manifold of my Vortec 350. These have the sealant already on the threads so you don't have to worry about coolant leaks at the bolt holes.

I had to replace a leaking intake manifold gasket on my ‘98 GMC 5.7 vortec motor. When I pulled the intake, several of the lower intake manifold bolts were very corroded. No way I was putting those back on. Got the new ones in within a few days of ordering. No issues, fit like they should. Hopefully the last ones I’ll ever need to replace. Very cheap insurance.

At first, I was concerned about the length of these, but I can confirm they match the mercury-speced bolts.

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

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 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.
