Most important first--it's Galleries though you'll see both used. Galleys
doesn't make much sense, galleries (being and opening, an alcove, etc. makes
sense.
There's nothing wrong with boring or honing a sleeve, it's just a matter of
machine shop quality. You want torque pressure applied during the honing or
boring.
Your choices come down to what you've got and what you want. If you have
stock sleeves and stock pistons and you're racing, now's the time to
upgrade. If your pistons are good stuff, then I'd certainly hone the sleeve.
Even if you took out .0015 you could still use the same piston. I might even
use the same rings, but I have these spurts of uncontrollable love for parts
I've already got.
Thing is, with a engine that's been running good, the only things I like to
change just for the heck of it are rod bearings.

Subject: Boring sleeves
Amichi,
Upon disassembling my motor (TR-4) to correct my discontinuity in the
crankshaft assembly, I discovered a leaking head gasket problem. It has
caused some rust corrosion in my number two cylinder wall lining; more than
can be easily rubbed out with steel wool.
What's the drill for boring sleeves? Pull the sleeves out and send them to a
machine shop or leave them in and send out the whole block. Or do can I buy
just new sleeves..or, am I now in the business of buying a matched set of
sleeves and pistons?
I'm most interested in reading the responses that say what I want to hear,
but all others are greatly appreciated.

Note: The head gasket failure is located exactly where Kas's book prescribes
his "staking the head" program. This begs a pretty good argument to go
through the staking exercise. Besides it looks kinda like fun.
The photo on page 48 of his book shows a crack in the head between two water
galleries. My head has this same condition. Is this an unhealthy condition
or simply symptomatic to TR-4 heads? One more question. Is it galleries or
galleys?
