How does compression and headwork affect a/f ratios?
Suppose I have a solid 13:1 a/f across the board with some lumpy cams...
How does raising compression from 10.6:1 to 12:1 affect my a/f ratio?
How does a nice port and polish of the head affect the a/f ratio?
I'm assuming they act the same way a nice flowing header/ exhaust combo work - and lean out the mixture because it's a more efficient burn/ flow... So adding more fuel will result in more power...
Anyone have some examples they'd like to share?

Re: How does compression and headwork affect a/f ratios? (Black R)
With higher C.R. it is preferable to run a richer mixture to avoid detonation but the C.R. should not affect directy the a/f ratio (like a good header would lean out slightly the mixture)
The head work should increase the a/f ratio because of better air flow.
