Thanks
Yer Clinders are supossed to be honed for several reasons, honing leaves a Dimond tyoe pattern nof small scraches in the cylender walls, these are nessesary.

Now as for the ridge, as the piston moves up and down yer rings scrape the walls and remove more and more metal, put one of your pistons to BDC and look for a Landing or ridge at the top of the bore, this is were your piston rings stop at TDC, if you have a rigde its bad, it means you have worn away alot of metal, when I took my 302 apart the pistons punched my bore .035 over so I had no choise but take the block to the machine shop and have her bores .040 over. If you have a ridge it means you'll most likely have bad compression cuase yer piston isnt riding as tight as it should be.
to check for the ridge the easyest way is to put yer piston at BDC and lightly run yer finger up the bore, at the top you will feel a bump or a smag, thats yer rigde, get it gone if you have one.
