looking for a decent set of headers for my 95 z. preferably part # 70-1335.

I would also take something similar that will bolt right up like they do.

 

Put these in while the Trans is out, just advice from experience. I installed my headers while mid-six speed swap, they are only shorties, but they went in super easy without the Trans in the way. Even if you leave them loose so they move a bit while putting the Trans in, you'd be in better shape!

 

I have a set of JBA stainless headers with the egr bungs welded closed with o2 sensors in them.
