<VV> cooling question

No! No rule of thumb. But just remember that the under-cylinder air baffles are designed to limit the amount of cooling air that gets directed to the cylinders and directs the air over the heads. Cooling the heads is the important feature. Little cooling is done at the cylinders so broken fins are essentially negligible.

I have a question. Is there a "rule of thumb" for how many broken fins are allowed on cylinders for them to still be acceptable to use? 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. Thanx
