Flycutting .080" is how many cc?

I'm not a mathemagician, but what's the generally accepted value if you flycut .080" to clear a 2.04" valve? Is it 1cc? A half?

That's what I thought. If I cut the exhaust .040 to .060" would be roughly 1cc as well?

Thanks for this thread. I'll probably be taking .100 out of both, per Mikes recommendation at New Era.

Bandwagon question: every cc you lose, what is that equivalent to in compression? Is it variable?

Not thread jacking again but do you lose compression from the reliefs?

On a 346 every cc taken out is approx .15 of SCR. So 2cc kills .3 SCR. Not insignificant.
