Just an educated guess..but most likely not.
It may have to do with oil pan clearance.
From the heads down, the only difference in LS1/LS6 to LM7 configuration (externally speaking) is the oil pan.

so the headers will bolt up to the heads but hit the pan on a LM7 but not an LS1 ? is the lm7 pan that much differant than the ls1 that the collector will hit??? or something else ?? im looking for and inexpensive header for my 78 C-10

They will work just fine.
I have never seen a header not fit because of an oil pan. Lsx headers are pretty much all interchangeable.

Those headers actually look just like the ones we recently put on an '08 5.3L swap.

Thanks for getting back to me on that, im hoping those header will for for my 78 i was just wondering if the collector will be behind the engine mount, if so then it should be good to go on any 73-87 truck with a 5.3
