I haven`t tried any other headers yet, but on my 85 Mustang, I have a set of long tube "equal length" FlowTechs, which have 1 5/8" diameter. They fit well with the factory K member, clear my McLeod scattershield with no need for modifications, and they have a couple of slip tubes, but with the collectors welded to several tubes, no need for the collector tether nonsense. I install the engine with the passenger side header fully bolted up, with the clutch, scattershield, and starter motor installed, once the engines in, the drivers side header slips in from underneath, with 1 slip tube to clear the steering shaft. They even have decent ground clearance. The best thing is that they are priced less than most 5.0 "shorty" headers, plus they have O2 sensor bungs welded to the collectors. Great bang for the buck.
