i'm looking for both, it's a stock ls1 thats getting stock ported ls1 heads.

gaskets
i need to buy the gaskets, does anyone know the gm part number? i can go to summit racing up the road an hour but i want to make sure on my end i know what to order. i've walked out the door with the wrong part many times.

bolts
i know i need the pre 2004 with the long and short bolts which summit also has, i wanted arp's till i saw a $150 difference which i cant warrent to spend on a stock set up.

this should be just a simple head gasket job, but i want to make sure i get the right stuff.

Do you still need the info for those parts? I just pulled my heads to replace the gaskets. Honestly, I got GM bolts and they cost $150 (and that was list price through a friend that works at a dealership) so I think it's better to spring for the ARP bolts and studs. And don't worry about paying that money on stock heads because unlike the stock GM bolts, you can re-use ARP bolts/studs. So down the road if you do anything bigger you'll already be set. Also, you won't break an ARP bolt or stud (learn from me)

I'm not home right now but I can get you the part #s when I get back.

Yes it should be 3 different sizes but double check with the dealership. Different years were different with the shorter bolts I believe? My '02 had 5 small 8mm bolts, 2 short 11mm bolts, and 8 large 11mm bolts.

But again, I stress that it's better to spend a little more and get ARP bolts or studs that won't break and can be re-used.

I bought myth headgaskets from rockauto. Oe headgaskets are made from Victor rienz and are significantly cheaper there
