best HEI timing setting for smog check?

[monster man]

what is the best setting in degrees for an HEI 350 4 barrel for a smog check?
last year, the tech says I barely passed, I told him that the only thing I had changed was to an HEI ignition from a points setup, he told me my ignition was probably too far advanced, that HEI's don't like barely any advance. Before, my points were set at 8 degrees advanced, so this year I have it down to 6.5 degrees, and pretty lean, and she's running like crap. Well, not stumbling or anything but a pretty rough idle, and she dies when cold. Definitely smells very very lean, so it may pass, it may not.

But, is it true that HEI's are generally set closer to TDC than with points?

I think the timing is for the spark is in relation to the rotating assembly. It should not be matter if you have HEI or points. I'd make sure you have the same curve for the advance systems.

thanks- I'm not sure what the old curve was or the new, but they're both vacuum advance and I almost failed on the idle test, 2500 RPM was fine. So, I'm assuming he meant the initial advance was too far, so I retarded it a couple degrees, we'll see if that works

don't run it to lean if you run to lean you will fail as bad if you ran rich
