I researched, asked for opinions, listened to a bunch of UTube videos and wound up more confused than when I started.
Finally I came across a how-to article from FSP Exhaust and liked the setup pix and content. So, I bought my dual outlet ceramic coated header from FordSix (perfect fit), 2-1/2" GT exhaust kit (no crossover pipe) and DuraMax Turbos from JEGS. Put it all together and she runs like a raped ape and sounds great! Stock 200 motor with DuraII and GM HEI module and H/W 5200 carb.
One problem, now with the extra power, the clutch REALLY slips when you put your foot into it.
