[Healeys] Denis Welch Tappets Again

[Michael MacLean]

As I get closer to starting my 100 engine I have yet to replace the
modified Denis Welch tappets like a list member suggested I do.  I got
nervous, so I ordered a set of NOS tappets from Ahead4Healeys to swap with
the installed Welch tappets recently.  Now, searching the archives, I  find
someone had problems with NOS lifters after 6000 miles. Ruined a cam and
the lifters.  So, what am I supposed to do now?  Should I just buy
aftermarket tappets?  Are the aftermarket tappets hardened correctly?  Why
wouldn't the NOS tappets be hardened right?  I don't want to replace the
cam after I get this thing running.
