Can step decking only be done on sleeved motors? how about open deck or closed deck?

Thanks,

I suppose you could have a machine shop shave down the deck (not including the sleeves) of a stock block, however I would NEVER do this and it probably wouldn't work to well... It's a different story with a sleeved motor as the new sleeves are pressed into place... Though there shouldn't be play there sometimes can be (we're talking 1/1000-10000th") this is why sleeves can sometimes drop... This extremely tiny margin of play allows the sleeves to drop ever so slightly as you torque down the cylinder head... As you can imagine this won't happen with a factory sleeved block, you would most likely have a gap which would be prone to leak both coolant and oil... Just my $0.02, I could be wrong

Sounds good to me. I always wondered whether or not step decking played a role in all the sleeve sinking issues that seem to plague some sleeved blocks.
