Default help please

Ok i have a 92Z28. I ordered headers for it from summit and i don't know if they'll work. I have a single cat and they say all the 92Z's had double. but one guy sends me headers for a 91tbi saying they will work with my set up.
Will they bolt up to the heads right. I know it's not na LS1 but I was just hoping you guys could help me on this. Thanks

My 92 Z28 (305 with auto) only had one cat also. I know the manual 305 Z's had dual cats. Not sure about the 350's though.

As far as the TBI headers being interchangeable with your 92 TPI, not sure.

Check out: http://www.thirdgen.org/ for some good info. You'll probably have better luck on their message board.
