leakdown in sylinders, how much is acceptable?

[erlendch]

Another question for you guys. How much sylinder leakdown is acceptable before I should consider it beeing worth a rebuild.

When does it start impact hp and torque?

Thanks!!

Did I read 80%, there's lots of possible reasons for excess  leak down, show us the spark plug to that cylinder, bad valve , head gasket, you got any signs of water in oil , using excessive amounts of coolant, ? What were the systems that led you to believe something's up

80% was in the cylider heads, which I will be replacing. The block was around 20% if I remember correct.

Not sure how they came up with that kind of break down, but if 80% of it is in the head, replaces the head? 

What kind of problem are you having? Just running poorly, give it gas and it smoking, smoking on start up or just using a lot of oil? 

Where did the idea of building a stroker come from, you or the repair shop?
