Oh NO!! not another small block build
on the suggestion to wire brush the decks ok
but do not EVER use a lapper wheel or a scotchbright pad
that thin dust will get into everything and not even a power wash will et it all
also no WD 40 it get's down into the pits of the steel and will not come out
just use ATF or some specialty stuff on the bores depending on how long till assembly keep wiping with old clean t shirts till no grey appears then do it again
DO NOT USE SHOP RAGS- EVER
cheers
