What headers to use?

[zapco23]

I recently bought a '69 Camaro SS/RS with a '95 LT1 Vette motor(yes, I know it's a mid-90s swap but I have to live with it until I can get an LS) and tranny swapped in it. Question is:1)Do I get a shorty header for the '95 LT1 Vette motor OR do I get a header for a '69 Camaro SBC? 2) Looking to also buy a MagnaFlow #15896 exhaust 2.5" tubing. I'm new to this and never dealt with a swapped motor so I don't want any fitment issues. Thanks!
