72 suburban change out

[madmaxburban]

My winter mission pulling out 402 turbo 400 auto and installing 502zz with TKO 600 5speed standard clutch. Now this is what im wondering with non hydraulic clutch is the linkage goin to become a problem to hook up with me running headers as well or am I goin to have to get some custom made headers so the brackets and linkage will clear. Just a thought before i start or if anyone else has done this before any info would be great.
