I would be more worried about the different overlap and lash with mixing cams. Its not just the duration and lift you need to compare. If you were rebuilding the head, re-shimming it and then using adjustable gears maybe you could get them to work together. The effort would surplus the gain over just finding a good pair of oem/aftermarket cams.
Are you saying that there's a potential that it won't work, or not work well, mixing 20V and N1?
