for 90's 302 block what # grit Flex-hone to use? What rpm for the hone and how many passes aprox to get the 60* crosshatch. Standard bore and cylinders appear to be good on taper and roundness when checked. Moly type rings to be used. Thanks

 

Technical information on using engine hones, flex-hones, ball hones

This site has you covered .

Biggest thing I would worry about is getting the loose grit out of the pores of the cylinder wall after honing and not oiling them into the pours .
