if the exhaust on the 200 was on the other side of what was in your van,
than you did not have a ford 6 cylinder in it. the 144,170,200,and 250 all
use the same head design. the diference is in the valve sive, carb opening
size, and exhaust size.it is not uncommon to put a 250 head on a 144 or 170
as a hop up to gain power.
a good reference book to have is the ford falcon six cylinder performance
handbook ,by dennis and david schjeldahl. it goes into detail on building a
killer six cylinder ford.
