Default Early headers on LT1?

What is the difference between the pre-'92 headers and LT1 long tube headers? Will the early headers fit on a LT1? Seem to be more choices (read cheaper) for early long tube headers - what gives?

Thanks,

The main difference is the Air Injection fittings. I believe they do fit the LT1 although I can't verify how good.

Everything bolts to the heads fine, they just have different clearance issues to deal with. Lots of LT1 guys put the L98 headers on.

Just bank on some customizing to get everything to fit together.

forum member - redbullapril23 tried it, unsuccessfully, with his LT1. I think he got frustrated at how much everything had to be custom fit.

Maybe he'll chime in.
