They may have changed the design--they said if you rotate it through by hand
and nothing interferes you're good to go.
The pushrods don't come close to rubbing. Their design offsets the rocker
shaft to increase the ratio--I believe the rockers are nearly the same
length overall.
They said exhaust valves on the Healey stand up fairly far so interference
with the head is not generally a problem. They also said the majority of the
Healey sets they sell are 1.6s.
The only issues I encountered are a tight fit between the oil banjo and
adjacent stud nut and the fact the banjo has to be shimmed with extra
washers to provide clearance for the rocker's higher profile. This has the
effect of requiring even more care with the banjo bolt to avoid stripping
the threads in the hole.
Also happy to report no clearance issues with my Ray Juncal finned aluminum
valve cover.
