Post subject:  Block & head surface cleaning
What is recommended to remove minor surface oxidation and crud on block and head mating surfaces prior to gasket and head/block re-assembly??

Was thinking of bronze or copper wool but wanted to ask first

Thanks in advance......

Scotch-brite, carb cleaner, and elbow grease has worked just fine for me. I imagine bronze wool would be fine, but I couldn't say for sure.

Use a block sander with an old piece of sanding belt attached.
I use a long & stiff piece of milled oak as my sanding block... with the sanding belt stapled to the butt ends.

Pull the pins out of the block and go at it... using some light oil to help keep the sand paper unclogged and also hold all the grit / dirt in a "slurry", that can be easily wiped-up. ( I worry that bronze "wool" will get particles into places you don't want)

When flat sanded... you will be shocked to see at how uneven the block & head surface really are.

I just chuck a wire wheel into the angle grinder or a drill.
The wire wheel will not remove the cast iron, just the dirt and rust...

Thanks. I can't believe that in (mumble) years I hadn't thought of this.
And I have access to rectangular tube that'd work as well as the wood, to boot. :roll:
