Has anyone applied thermal grease between their engine block and cooling head? If so was there a noticeable difference? Would there be any drawbacks to putting it on?

Just thoughts bouncing around in my head.

you dont need it, thats what the copper shim is for, metal to metal contact (with copper between) transfers heat better than thermal paste.
 
do you mean in between the button head and cooling head

would be interesting to know I'm guessing your thinking of the stuff used for contact between a CPU & cooler ect
 
I've never tried it but I'm thinking the difference wouldnt be huge but it may help a little bit. I kinda doubt it would help enough to make it worth messing with.
 
I kind of doubt you could even measure the difference with the best equipment if there was any to measure.
 
you may see some difference when its idling but when its getting airflow over it I think Snook is right...probably couldnt measure the difference.
 
it would squeeze out and make a mess that would attract dirt. making it pointless.
 
That's something used on heat sinks for CPUs or output transistors, neither one really getting much above 130-140.
I think it would break down at the temps of these engines.
 
Hmm, maybe I'll do a little science experiment and see what it does at different temps between 200 and 300f. I have a bunch of real cheap stuff.
 
Try get the silver thermal paste. From memory it actually has silver in it and transfers heat better. It only helps on computer cpu's as the contact area between the top of the processor And bottom of the heatsink are both hard metals and the actual contact area is very limited. So the thermal paste goes into the small areas that don't contact properly.

When using a head off a nitro motor there is a copper seal between the two to the contact area is a lot higher than a computer cpu
