Obviously having a can or two of CRC Brakleen for cleaning is an absolute.
For cleaning out the cylinder bores, we always us Goop Multi-Purpose Creme #12
(Hand Cleaner) and paper towels. You won't believe how much more grit that creme picks up off the walls.
If you're not assembling the engine soon, coat the cylinder walls with Marvel Myster Oil, and wipe all machined
parts with the stuff. It is a fantastic product, and fairly easy to clean off the parts before assembly.
Using 3M Scotch-Brite Pads (Light Grade) works wonders, for removing any metal burs off the pistons, before the ring assembly.
Make sure you run a brush (or pipe cleaner) through the crankshaft oil holes. Blowing them out with air only, will 'not'
do the proper cleaning.
On the Top Piston Ring, .018 is correct for the 4.350" bore.
A suggestion would be to purchase a set of Speed Pro or Sealed Power .030 over + .005 Rings, and file fit them for proper clearance.
