Sbc 350 in 84 cutlass questions

[Timscutlass]

My first question is, I have brand new long tube flow tech headers for a 84 Monte Carlo, I read to use everything off a Monte Carlo g body car so that's what I did. Will I need exhaust modifications for the long tube headers to work or will they be a direct fit?

Also I got frame mounts off a Monte Carlo ss. They should be ok right?

Anyone know about the headers?

70% chance they will fit. Minor tube denting on driver side, maybe.
