Hardblock?

Do you use a half fill or a full fill? Do you put a gasket and head on after filling that side of the block so the bores are distorted in the same way as when running? I was thinking of buying the full fill Hard-Blok and then using half in my 273 Mopar block (and 1/2 of that on each side). I've never used this before, but the cylinder walls on the 273 blocks are under .200" thick, some down around .130" with a standard bore. The cylinder walls tend to be thinner in the middle and the front and rear areas between the cylinders.
