I cant answer the hone size question sorry:huh:
But get the field service manual and the other is make sure you lap the head and the block properly. Why the lapping effort...that what my mechanic did and I lost all my water twice due to hose failures and did not blow the head gasket.

Other than that get OEM components if you can...good luck

I think I replied to your question in another forum - I'll summarize that here - from the questions you're asking, you seem to lack the experience required to tackle this project on your own.

These engines are simple and not difficult to rebuild, but if you lack experience, it's highly recommended that you find someone who can look over your shoulder and guide you through the steps involved in the rebuild.

The size hone will be dictated by the size bore (and that information is in my other reply), whether of not you need to hone will be determined by what you find when you tear down the engine and measure the wear.

As for lapping the head & block - you're basically ensuring the mating surfaces are flat & square so they will seal properly - I'm also going to point out that lapping the head/block may not even be required - what IS required is that you check it with a straight edge & feeler gauge to determine if it needs to be done.

You can do an "eye-ball" assessment if you want - it's your engine - but - if you can detect wear and "out of roundness" with the naked eye, then you don't need my advice, and you probably wouldn't be asking what size hone to use.

You have to know your limitations, I can only guess, based on the questions you ask.

FWIW - the last G13 I pulled down had no wear ridge at the top of the bores and even had factory knurling visible on the pistons - when miked it was within acceptable tolerance, but just barely, the machine shop suggested honing & new rings, but when honed, it was outside the limit - I bored it oversize.

Bottom line - it's YOUR engine.
