Reconditioning the Block prior to Head Install

[rapieper@yahoo.com (Ron Pieper)]

I use a steel wire brush and a stone on the block surface, with plenty of oil.  By stone I mean a
nice quality new one, which reveals any high spots.   Sandpaper...maybe 320 wet/dry for tough
spots.  I use light oil when stoning, for cleanup I use brake cleaner or lacquer thinner. 

Don't forget to retap your head bolt holes!

Since I have a stand I flip the block nearly upside done and spray the MOAB of the piston heads,
walls, bolt holes, etc. letting the drippings fall onto newspaper (NY Times if possible, or USA
Today in a pinch).  Then wipe butt-clean with no-lint wipes.  I do lightly oil cylinder walls. 
Deck surfaces MUST be desert-bone dry before gasket install!
