Hard Blok water jacket filler

I am slowly piecing my 7.3 back together from a scored rear cylinder, that dumped diesel into my oil, so far I have a fresh .020 block and a turbo reciprocating assembly, that I still have to massage and assemble, I wonder if I fill the coolant passages half way with Hard Blok filler after I done the boring and honing, will it be an issue? Why did I wait till now to think of this???:icon_rolleyes:
always happens this way. since these engines are a little thin I don't see any problems doing this. anyone else thought of this? also anyone have a good set of bare casting heads?

I too believe you would lose cooling capacity. It probably would never show up in the water temp but the cylinder wall would get hotter, and possibly score the piston again. It'd be nice if you could get an 1/8" coating through the entire water jacket, but I don't believe it works like that.
