Those tubes are not typical of what you would see on a 70 BB Chevelle, Camaro or Nova.
The capped design was the first design to show up on 69 model year Chevelle, Camaro and Nova.
2nd design 69 tubes should be a 2 step tapered passenger side tube (which carries over to 70) and drivers side tube was the crimped ( or pinched style ) like what Phil is describing.
1st design 70's used the same tubes as the 2nd design 69's.
2nd design 70 tubes were 2 step tapered on both sides with a redesigned drivers side tube that pointed the long hose over the valve cover instead of around the front of the cylinder head.
The set pictured are 1st design 69's in my opinion. Look like real nice set of originals.

Thanks guys for the reply. Much appreciated. Does anyone know when the break off point of when these were last assembled. Would they be correct for a early Feb 69 Camaro? If not I really have no use since I have nothing built earlier. Thanks guys.
