Default ls6 vs ls2 coolant crossover

Front coolant crossover pipes, I believe the part #s are:
ls6 12602544
ls2 12602548

Anyone know what the difference is, and will the ls2 version fit on an ls1?

I need to know this as well. Installing a Fast 102 and I have the LS6 2544 front crossover tube already with the 5.3L crossover in the back but 2544 is giving me fitment problems.

2548 is ls2/ls3 crossover and possibly a different design?

Well turns out you can get them on ebay, with pictures and everything (search on part #), and see the difference. Pricewise, I'd check sdparts.com.

Doesn't look like the LS2 would work on a Fbody

Googled both part numbers earlier, pictures are easily viewable but has anyone used ls2/ls3 crossover tube successfully on ls1?
