Go to a GM dealership and buy a set of stock exhaust manifold gaskets. They'll work fine.

they do come with gaskets.,.. but the gaskets they send are worthless and tend to leak...

you can just reuse the stock ones...

also... make sure you get the car high enough in the air to put the drivers side header stright up and down to get it in... if you dont get it high enough to go straigt up and down with the header you will be cussing all night long at other parts of your car...

and I highly recommend using the bolts that get sent with the kooks headers...just dont over torque them...
pass 1 = 11 ft lbs
pass 2 = 18 ft lbs


also depending on what exhaust you have going with it.. you will want to leave them loose until you get the x-pipe or y-pipe connected to them, after that you can tighten the bolts down

I would reuse your factory gaskets if they are in good shape. If you need a set, we have them on the shelf and can get you fixed up! Let me know if you have any other questions!

my best investment on my car, without a doubt

ARP HEADER STUDS

they eliminate all the shitty parts about installing headers. That pain in the *** last bolt on the drives side, no problem. I've done 5 header installs on LS1 F-body's, and refuse to do them without the studs. they cost $100, but are worth it, EASILY. I think the worst part about installing headers is having to try and hold the header, gasket, and somehow get the damn bolts in without cross-threading the hole. Where as with the studs, install them, slide gasket on, slide header on, and apply washers and nut, tq down, and go have a beer

FYI, I did 4 of the 5 installs by myself

If you make two temporary studs buy cutting the heads off two bolts and knotch in a screwdriver slot. Hang your gaskets on the temp studs, install headers thread in permanent bolts then remove temp studs with a screwdriver.

Everything from ARP is expensive, it's top dollar quality ****! Would have been awesome to have those when I installed my Kooks.

Ditto on the MLS gaskets too. Those felt gaskets that most header companies include will leak in no time. You'll be doing it again soon if you install those.
