one mans humour is another mans sorrow
its very restrictive gallery wise, i would never bother fitting them together, but others obviously have so have a butchers at the 2, see what you think
custom gasket would be useful too as neither lined up properly (mind you neither does the z20let but many do just drill them and fit anyway)
the xe gasket shrouded the valve area and both didnt line up for galleries iirc
i didnt spend more than 20 seconds on it tbh as it was too much effort for the gain imo
