You mention that it has been sitting awhile, how long? I would go through it...new rings, bearings etc. To give you an idea...I rebuilt my block in 2004, and it has seen maybe 10k miles on it. I am about to send my head to be ported, right before i go to Iraq for a year. Now I am pretty sure that if I fill the cylinders with a good thick weight oil it will probably be fine when I return...but I aint gonna take that chance. During my deployment I will source NEW 1mm over pistons, rings, bearings, etc so that when I return....all I have to do is get the block machined, rods prepped, get everything balanced, and then throw on my newly refreshed head. What I am trying to say is, at i minimum...check the bores (dia, gouging, etc) Ball hone, and throw some new rings and bearings in it.
Nothing sucks more than putting a head on a supposedly "good" short block, only to have it smoke like a cheap Havana Tampa cigar
