Best fit SBC 700R headers 72 C10 ?

[6pakdave]

Hi guys, Im looking at buying some 1 5/8" headers for my sbc with 700r truck

I am looking at the Jeggs product #555-300111. They dont say if they clear the 700R tranny [com shift] though

Any help on what headers fit and clear the best for a SBC in a 72 C10? P/S A/C

cheers Dave
