The stock Healey 6 cylinder lifter is a pedestal type of lifter that fills up
with oil. It is not the best design for a performance engine. You have to
grind or machine a "flat" at the lower part to allow the trapped oil to get
out and down onto the cam.
A bucket lifter has better geometry because the lower end of the push rod is
much closer to the cam. The MGC lifter is a bucket lifter that has the same
outside diameter as the Healey pedestal lifter. The MGC lifter also has an oil
hole that allows the oil to drain out and down onto the cam. The MGC bucket
lifter is about one-third the cost the of a Healey pedestal lifter and is
about 1/3rd lighter.
The only added cost of using the MGC bucket lifter is you have to special
order longer pushrods and - the socket on the MGC lifter has a different
radius than the Healey lifter.
