I'm about to install my MAC headers + ORY. for 2001 Ls1
I got them in a very good condition for low price, but I didn't get any bolts with it.

My question is if need any, or can I just re-use the stock ones ? (I'm talking 3 bolts on each header flange, and the Y-pipe bolts...)

If I do have to order those, when is the best place to look ? MAC Performance itself ?

Thanks

Stock header/manifold bolts should work. Sponsors have them as well. ---->

as stated above you can go ahead and reuse your stockers. Or if you want you could spend some cash with a sponsor and get a nice set of header bolts.

Thanks a lot guys ! In that case I think I'll reuse the stockers for now. My SS has only 17,000 miles on the clock. Bolts should be in good condition....

Again - Thanks guys !

I used the stock bolts on mine. They work fine.

and you can get grade 8 bolts at lowe's or home depot for the ball flanges on the y

I'm not sure what I'm doing yet. Thinking of going with the Grade 8 locking bolts. I'll probably use the stockers for a while.

My car has 53K on it...should I get new manifold,EGR and AIR pump gaskets when I put mine on?

it all depends. sometimes they come off clean and can be reused, and sometimes they rip apart. for extra insurance id get some. then if it happens youll have them handy

I vote locking stainless steel header bolts, the last thing you need is an exhaust leak or broken bolt, worth it imo
