Hi Chuckster,think you need to attack the issue in the following way,
1) compression test and leak down test,if it's being lost somewhere it doesn't much matter what lift,timing or compression ratio you have.
2) whilst you have the plugs out check the colour,my gut feeling is running weak,maybe check the fueling with a wideband,everything in (1) wont matter if the fuelings bad
3)double/triple check the lobe centres to make sure it was right/hasn't slipped if your not making good power from 3k up its lacking more than just extra squish,

Good luck before it gets icy! Brittrip.
