CMI SportTube headers
Includes Bolts, jumper hose, and clamps...
No tails

The headers are in mint shape, look great, no rust, pressure tested over night with no drop, also sprayed with soapy water and dunked in bathtub with zero signs of leaks

Asking $3000obo + shipping from NJ

Does this set of headers fit the 525 EFI? How many hours of use do they have.
Thank you

Yes, they are the 525/600/700 style, but of course can be cross drilled for standard BBC, similar to how the Gen-X headers come drilled.
I got them as part of a package deal but only needed the 1 set... P/O said ~270 hrs, and I have no reason not to believe him. Only sold because he swapped to QC4V motors from 700SCI. These are in mint shape and pressure tested no issues and look internally great.

this set looks to be straight back possibly from a staggered boat ?

Yes, They are straight back style
