no coating (i'd destroy it anyways lol) the protective paint they use will be sand blasted off and re painted with the same alum high temp paint that we used on the 442's LIM/Exhaust (held up damn well except for 4 rust spots from not doing enough surface prep)
this is of course after both sets get O2 bungs welded into each primary, ported/rewelded (anyone thats seen the weld quality would prob do the same) and a couple tabs for a bolt on Y pipe, and removal of the EGR stovepipe/flange section to clean up the #6 primary flow.
once we are satisfied with the headers (prob after a year) we'll likely get them ceramakromed to match all the polished aluminum a bit more
the whippled Riv just needs its primary O2 bungs welded in...dont know if eric will get em coated or not...he prob will...i mean its gonna have a SC snout to TB measurement of over 3 ft![]()
