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'm way behind on this, but there are a lot of engine builders who fill these blocks as much as 1/8" below the deck with hard block. They say it has no effect on daily driving and towing. It seems to me like it would, but I've heard several say you'll never know it was done.
