If they both yield about the same HP increase, why would you go with 1.7:1
rockers? Please explain in simple terms as I'm new to this aspect. ;-) Also,
if 1.7:1 are the best choice what are all the parts that should be replaced to
be absolutely sure there will be no failures or breakage. Lastly, will the
1.7:1's fit under the stock valve covers?
TIA

1.7 and 1.6 roller rockers will give about the same amount of hp increase. main
difference is the length of travel of the arms. Some say the 1.7:1 is too much
and worry about movement of the pushrods and misalignment. The roller rockers
tend to take care of it though.
