header install parts that are required?

[blue02Z]

what are the best gaskets, bolts, o2 extensions, and o2 sims to go with for my new headers? also where to get them on the internet? thanks everybody

[Zboner]

for best gaskets go to GM and get the stock gaskets for the exhaust manifolds

Get percys aluminum gaskets and breslin bolts; If you want the best.

Also agree w/ the stock gaskets, they are steel and work great. Bolts, I just reused the originals dont see any need in changing em unless they are real beat up. 02sims, Doesnt really matter...they should all go for pretty much the same price, look at the sponsors and see what you find.
