check with cometic gaskets. They seem to have a gasket for everything. Why do you have copper gaskets??? They ping and click at start up everytime you start the truck up until they are seated and have heated up.

 

which gaskets should i get???

i went to the chevy dealership, and they told me they cannot get any OEM gaskets??

so thats why i am on my own.

any help i would appreciate

 

What kind of dealership can't get OEM exhaust gaskets? The Oems are what will work best.

 

if yourasm's are new they should of came with it.

 

SCE 2.5" Pro Copper Embossed Collector gasket

Part # 4250, got mine from Summit Racing

 

Run the stock gaskets, 12558573. Dont even bother with the paper crappers.

 

I install only GM gaskets on my truck...and did so when installing my headers.
