Does anyone know a good source for small block olds headers for gbody (cheaper the better) or some cast duel exhaust manifolds? Really need to open up the exhaust on that diesel. Even the stock pipe is this tiny little thing that doesn't have a place on so much as a 4 banger
 
Thornton makes dual exhaust manifolds but the gain would be tiny. The Hedman full length for the Olds V8 in the G body are the best deal.
 
Idk how much the gains would be but you should see these things. Looks like the manifolds off the little olds engines with small flange openings. The exhaust pipe itself is smaller than any ive seen even on a v6.
 
I bought one already built, and it runs like a beast!

I think he meant it is a DX block converted to gas.

If the head ports are tiny putting different exhaust manifolds and or headers wont do much of anything.

If anything the Olds V8 ports are too big, compare the aftermarket aluminum heads, they all have the floor raised and the ports shrunken. The diesel heads are no different, too big.
