crf, I think your info is correct, I thought Shibby was wanting info on these heaaders, the 525,600,700 have Edelbrock alum heads with the non standard flange bolt pattern

Exactly. The new Gen X's are drilled for both the Edelbrock heads and standard Chevy pattern. And like you said before all the "sweepers" have the same header to tail flange.

still for sale?

Sure are

The mark on the one header is from the bimini rubbing it. It is not a dent.

if only thru hull tails were readily available on the used market. CMI just wants so much money in my opinion for a tail kit. :(

But keep in mind your getting 8K worth of headers for 3K, this is a good deal
