Don't remember Waynes method, but the two I know of are:

1. Drill guides with a drill just a tiny bit small than the OD, pick the remaining out.

2. Take a bar sized to a slip fit of the inside of the guide, with a step milled in as a stop, place in freezer, Heat the heads with a torch, place bar into guide and knock out. This is the method we used to use on light aircraft engines. In a production shop we had a fixture that held all the cylinders of a row of torches, so they could all be heated at once, then they were rotated and there was a set of drivers in the freezer so you could do them all at once. The guy who did this job could replace a full set of 6 in about an hour, including removing, sizing and driving in, reaming and sizing the bores.
