If the clearance is tight , you need a thinner pad.
If the clearance is loose, you need a thicker pad.
For arguments sake, lets say you have 0.07mm clearance on the inlet 1 and you have a 180 pad in there. To get the clearance up to spec you would install a 175 pad. That would give you 0.12mm clearance. I assume the 400 has the same specs (In 0.1-0.15mm Ex 0.20-0.25mm)) as the 426.
You dont have to worry about buying a new head, or even valves for that matter. The WR400 has steel valve. This means all you have to do is get someone to grind the valves and seats, and then 'tip' the valves so you are back in the middle of the shim range.
Hope this helps
