what headers on a 4wd big block with a manual

[MAC67]

Hey guys , been out of the loop awhile .

This is the skinny , building a 70 gmc 1 ton 4wd for a buddy of mine , Its getting an injected 468 , d60 front 14 bolt out back with air lockers and all the goodies . Sticking with the stock manual and 205 , trying to make the truck stock appearing with all the goodies well hidden besides a pair of 33inch swampers.

Im getting all my eggs in one basket and looking at possible stumbling blocks down the road , So you fellas with big blocks in your 4wd's and manual trans, what headers did you run to clear the linkage, or did you even have a problem with it?

Thanks in advance .
