<VV> cooling question

[Bryan Blackwell]

I'd say anything up to a thumbnail size chunk should be fine, really I'd only be concerned if a couple fin sections were missing entirely as that might affect the stiffness of the barrel.

My other thought on this subject is what pistons you're putting in?  Check the bores for both size and straightness too.

I've disassembled a parts engine and found a couple of cylinders with minor damage.  I'm wondering about this because internally they show very minimal wear and i'd like to re-use them, if possible.
