Also Joe at CPR recommends 2 inch headers on the new LT motors, said the 2 inch headers made more hp and tq across the rpm band.
Here back to back testing it says the 1 7/8 was better down low but the 2 inch did make more at 6000+ so the 2 inch still made more power.

Here 2 basically identical cars were tested and the 2 inch headers made more also.
