I no they have different heads, apparently the 200 has been 'tweaked'. I want to no if there is a significant difference between the 2 of them. Looking to find out if i have a restriction in airflow etc on my 197 head? I cant imagine there being a huge difference, maybe more for emmisions/MPG?
No guess work please boys, im looking for info
Thanks
