Changing lie angle on PXG irons 6,7,8,9,W,G,S

Bought a used set a couple of weeks ago and my misses are fat and to the left. Lie angle seems to upright. Thinking of taking them to Golfworx. Read that 3 to 5 iron should be standard. 6 to 9 should be 1/2 flat, W and G should be 1 degree flat and SW should be a degree and 1/2 flat. Any thoughts on progressively changing lie angle as opposed to having the same lie angle throughout. Thanks.

Best to check all of them separately. Some could be out of specs. Use a lie board or put masking tape on the sole of the club. Head to the range and hit off mats. If the mark is in the middle then the lies are fine. If towards the heel they are too upright.
The more lofted clubs will be the worst ones of the bunch.
