If you look at the pics in the original post, you'll see what the bores looked like.
I spent what felt like forever going through them with a drill mounted brake hone, until they felt/looked smooth.
What bothers me is the pistons in the aftermarket rebuild kit (the pic in your other post is what I bought) would not return under it's own spring pressure. Orings that came with the kit were 1-1/8 OD x 1/8 thick, I replaced them with 1-1/16 OD x 1/8, now the pistons will move. The diameter of the groove in the piston still held the oring out far enough to seal...not leaking yet, but I don't trust it for the long haul.
That's why I was looking at the MC for the chevy...honed right instead of me with the drill hone.
And now you've got me wondering if the aftermarket kit has mineral oil seals...guess I'll find out.
Guess I could put the rebuild kit in the chevy mc...unless they used oversize pistons/seals after they cleaned up the bores.
