Default XJS-LS1 Headers

Deep in a 92 XJS Convertible V12 receiving a LS1 with LS6 intake/799s/Pat G custom Comp cam/4l60E. I've got the Jag Specialties kit, engine/trans are in and I have the C5 manifolds cut and fitted but would like to have long tube headers. Anyone know of any that work or approx cost for a custom set? Anyone been here?

Default Custom Headers

Currently I have a set of SS 1.875primary long tube headers being manufactured by a prominent NASCAR affiliated shop and may be able to offer similar sets to interested XJS/LS1 conversion owners. No dyno figures yet. Going thru a no cat 2.5" Magnaflow system.
