Any reason against removing a stock cam with 90K miles on it, keeping track of what lifter goes to what cam lobe, and reinstall the same cam and lifters back in? I know lifters are worn matched to each cam lobe, but if the original parts are going into the original block in the original positions I can't see any issues with doing this.
