If so how well do they fit? Also do you have any Pics of them in the car and how close do they come to the oil pan?
Thinking about a set for my Street car with W2 heads.

I had an old pair of big block 2" fenderwells and the fit and quality were good, but when it was time to replace them, the cost was 2X Hookers or Proparts. I got the Proparts and there was no difference in performance.

Been a set on my '70 Duster since it was new; it's always been a drag car. Slip-fit primaries, one on each side goes through the apron, collectors bolt on using tabs. Clears a huge oil pan & the trans, tight at idler arm. Tight at brake lines. Requires adapters at the cylinder head if your heads have the OEM bolt pattern. Flanges are real tight if you use 13/16" spark plugs, but 5/8" are a breeze. No interference with my 7.10x15 Moroso ft tires. No ground clearance issues unless your trailer lacks a beaver-tail.
Here's a left-side photo, with Batten W2 heads. Being an old SS/IA car, the engine location's been juggled a bit.

Does anybody have a set of $tahl 1 3/4" x 3" for A-body/SB? (stock heads)

I have a set of Hooker 5303 (1 7/8") and think 1 3/4" might be a little
quicker for my 340.

I think The $tahl 1 3/4 x 3 would be the best size for my mild 408, seems to me the 1 5/8 TTi step headers would be to small and the 1 7/8 too big.
Any one have a nice set they want to sell?

Here are the only pic I have, in a 68 barracuda! With these headers the car went 9.52@ 143! In street clothes!! Love them. And they might be for sale!! ! 1/3/4" x 3"

Any one else using these headers?

Do you still have the Stahl 1 3/4" x 3" headers?
