Think I will definitely swap the 4 that are on the bottom limits with thinner shims.
But MIGHT do 8 all up to balance things out a bit more...
The 2x 0.15 inlets, the 2x 0.22 and 1x 0.23 exhausts - I'd go for shims that are 0.025 thinner.
The 2x 0.20 inlets and the 1x 0.28 exhaust - I'd go 0.025 thicker.
