Header fitment advice

[carbon69]

Hey everybody...would just like to say this site has saved me many times through several builds. I know I haven't posted much, well practically not at all, but admit I visit here multiple times a day.

I'm at the point on my current build that I need to purchase some headers. A little about the current build;

1967 c10 swb step side, converted to 5 lug using 71 parts, 462 bbc, th400, POL tubular engine mounts moved to the forward set of holes on the frame rail, POL trans cross member, ece 4.5/6 drop and trailing arm crossmember, 20" ridler 695s.

The 462 bbc engine I built has sat for years, (still needing to be broke in) so I decided this truck would be the one. Getting a set of headers is the only thing holding me back. With the drop I'm needing as much clearance underneath as possible. I thought I was good ordering the hooker 2455s for a chevelle, but getting conflicting info. I do understand that it may be necessary to switch out my trans crossmember. Would I be better of finding a set of mid length chevelle headers instead, and if so which ones do you guys recommend??

Thanks in advance, pics to come
