Reconditioning the Block prior to Head Install

[txrocco@sbcglobal.net (Patrick Bureau)]

it is a chemical cleaning solution that eats carbon
and oily residues without harming the steel casting,
it will damage  the inetermediate bearings, but in my
case I did not care I asked the shop to replace them
at the same time (as they have the tool to place them
probably back in place) yeah I powder coated my block
as well :)

here is a before picture of my block
