running a lot hotter w/ aluminum heads?
ok as you may kno i just reciently did a mild build to my car. GT40X aluminums, f303 and explorer intake. it seems like it runs a lot hotter now w/ the aluminums. is that normal? i know aluminum has different properties than the cast iron. my temp never went above half before, usually hung around the 2nd notch. now after curising on the highway (70mph) for a while it will go up to the notch above half way. but if i get off the highway it will cool down more and be about half.
my other question is should i run a lower thermostat? i have the 195* in now. should i go 180* or even 160*?
thanx guys

fan works just fine because it doesnt get very hot while just ideling. and im 100% positive the HGs are on the correct way. i made a point to check it several times lol.
as for the radiator. um im not sure i mean i had to take it off for the build obv and it drained and filled fine.
ill try running a 180 and see how that goes

ya i burped it. i started it let it idle w/ the cap of let it get hot and squeezed the upper hose til i didnt see any bubbles. and the cap is tight and the spring feels stiff like it should.

lol ya i know referencing the stocker isnt good lol but i need to get some fittings for my autometer temp gauge. it just has the bulb on the end and i gotta figure out what fittings i need to get it to work. and all of the sensors and switches are new.
and i dont think it is necessarily overheating just running hotter than it used to
