Regular small block the center exhaust ports are side by side. The LS engines are spread further apart and more equally spaced on the exhaust ports. :no:

Never tried it, but you theory might work.

Look on Ls1 tech. A guy just did this, but he used Mustang headers, as the port spacing is very close. They were long tubes, so clearance is a crap shoot....they turned out pretty nice. Look in the conversions and hybrids section.

T,
okay I'll give it a look thanks for the information.

If you are looking for a cheap LS header option and you are willing to put in some elbow grease you should consider 4th-gen F-body Ebay headers. Stainless steel, 1-7/8" primaries, comes with hardware and they are under $200. I used a set for my 5.3L swap into my 73'. With a torch, a buddy and a 12 pack we were able to get them to fit pretty well. Check out post#57 in my build thread for details.

Now it looks like the fittment with the power steering gear will require some "custom" primary clearancing. Just an option to consider.
