Sharpening Japanese Iron

After making a few passes with a scraping razor blade to remove the bulk of the residual gasket material and a light once over with a scotch pad,

I remember seeing the use of a knife sharpening block to resurface the block on youtube... I belive it was Mighty Car Mods, Benny's Custom Works or the Skid Factory perhaps...all Aussies who collaborate occasionally.


I happened to have a sharpening block so gave it a go...


I have made multiple passes each time removing micro layer material...Cleaning the stone and the deck each pass...



At the stage where the deck is clean, there is some ingrained stain corrosion but the gasket sealing points seem all intact. The black spot cleaned up alright thought it looks like it seeped out and around the cylinder 1 ring...



Can't go too heavy or risk undulating the mating surface, but I think I'll do a few more passes tomorrow before considering installing the gasket.


I have to prep some ancillaries from the old head to install on the new head.


Also found some maker marks on the deck and pistons. So more evidence of originality.


All in all hopeful for a positive compression result.
