Though you may not have an overheating problem with these intakes,the "temperature sensitive" I refer to has to do with the actual temperature of the cylinders themselves by restricting the coolant passages,if all cylinders are equal in temperature they would also be equal in the amount power produced by that cylinder.As long as we are on the subject of heads someone on a budget may want to check this out:Six Budget Ford Heads That Work - Car Craft Magazine Note: that some heads have larger 2.02 valves,and most rebuilder style pistons won't clear those without some machining so keeping with a 1.90 or 1.94 valve would be a better option as far as cost.As long as we are talking cooling and aluminum parts if you want those to last please install this: JEGS Performance Products 51994, JEGS Anti-Corrosion Plug | JEGS Performance Products No doubt you have seen used intakes with corroded water passages,this is cheap preventive maintenance from electrolysis.
