small block chevrolet in a 68 barracuda headers

i can see several options here,some standard cheapy headers like hooker comps or flowtech 13100 for a smallblock mopar abody but there is a pretty big chance that they will interfere with the smallblock chevys sparkplug locations and you will have to cut the flanges of and weld on some chevy flanges and may have to wrestle alitle with the pipes since i think the pipes may have a slight diference in distance betwen each other. option two is if the car is a manual stearing car some hooker supercomps cant remember the partnumber put they may be the 5204 multi piece headers they may leave abit more space around the plugs if you have straight plug heads.once again you will have to cut of the flanges and weld on chevy flanges.
option 3 some hedman raceheaders for a W2 aplication you may get away with this and only have to fab up some diferent adaptorflanges.
option 4 some shorty camaro/chevelle headers not the regular blockhuggers i think the regular centerdump headers will give you alot of trouble with clearence around the steeringbox the mentioned chevelle/camaro shortys dump alot further back and will atleast fit your heads and work with the chevy sparkpluglocation may still get to close to steeringshaft.

but nothing is set in stone and i cant promise anything. just giving a few pointers as to what to look for the biggest obstacles using mopar abody headers would be sparkplugg location/starter location/oilfilterlocation wich is all diferent on a chevy engine

best option overall would be building something custom.

hope it helps alitle atleast.
