31mm nitrided race exhaust valves,
bronze valve guides
double valve springs

looks ideal, but you'll want to check where you compression ratio will end up with the bottom end you want to use, although with 27cc I cant see a problem

Depends on the quality of the work, & if it's been used at all check that the ex valves aren't sunk as you can't go up an ex size to reclaim the seat without offsetting the valve.
If it's a good job & in good condition the 36-31 valved heads do work very well.
