when: when you need to strenghten the tops of the cylinders due to added revs, high comperssion, or forced induction.
there are going to be mixed results to your answer. ive always heard that they are ok if you get the cylinders re-aligned with the crank rod journals after the install. some are totally against them because their best friend's, mother's ex-boyfriend's son had one gernade his engine after hammering it in with a rubber mallot and running the hell out of it.

This is a better question to ask in the forced induction forum.
Personally I'd never use a block guard. I'd either boost a stock motor, or do a total build with sleeves and everything. A block guard falls somehere in between and IMO they're not worth the trouble.
What car, engine, and set-up are you going to run?

A block guard is normally used in boosted applications. Honda's have an open deck design so there is a gap between the block and cylinder sleeves and coolant flows through there. Guys will install a block guard there for a little extra insurance to hopefully keep the cylinder liners from cracking as the stock ones will go around ~300-350whp.
I have no personal experience with them, but some people have had issues with overheating because they restrict coolant flow and also warping/ovaling the cylinder liners.
Personally I would do forged internals over about 250whp on a daily driver and I would spend the money on aftermarket sleeves over about 300-350whp. I am not a fan of the block guards.

Well if you're boosteing it then a block guard won't be needed.
Stroking the engine eh? Good luck. Unless this is a drag car, and you can afford to rebuild the engine again I would not bother stroking it. Stroking an engine is sually something resrved for guys with a **** ton of money who have already hit the limits of the normal stroke engine. Stroking an engine also redices it's lifespan because it creates more stress on the pistons due to a worse rod/stroke ratio.

I've allways heard that they cause the stock sleves to go out of round. There is allways two sides to the issue though. I know people putting down 400-650whp on stock sleeves.
