that looks sweet man - i love the rockers. Are these the same as the ones for a 6 cyl? are they stock ratio or higher? do you need different length pushrods? Also, my lifters are noisy - i should get around and change them - are the lifters more quiet with the roller rockers?
For your question about the intake - it always makes a difference if you get in colder air - definitely if you get hot air in from undernieth the hood (which i do too  :( ) it will lose HP/torque - hotter air means larger volume for same amount of O2 molecules so for same volume of air you will get less oxygen (plus the other downsides of hot air into the engine). You will still feel a difference at night even if you get a shorkle or air from somewhere outside the engine compartiment just because the temperature is lower at night.

Yes they are stock 1.6 ratio they are adjustable rockers so I was able to set the correct preload of .050 with stock push rods. My lifters only had 6500 miles on them so I did not notice a differance in nois level. also I bought the rokers from hesco and they are the same as the 4.0 he just sold me 4 sets instead of 6.With the adjustable rockers you will need a 1/2" spacer for your valve cover to clear the taller rockers and a differant thermostat housing and spacer to move the housing out enough to still get the radiator hose on with out hitting the valve cover pain in the *** but it worked.
