[Healeys] Rocker Arms - Austin Healey 100, early Austin A90 Atlantic

[Alan Seigrist]

Hi All -

My '52 A90 motor is almost identical to the Healey 100 engine in almost
every respect.  In doing some work on it, I've pulled the head and I was
very dissapointed to find that the Banjo Bolt attachment point on the Rocker
pedestal is completely stripped.  Also, one of the push rods is bent.

Luckily, I have a spare A90 motor, which I figured I can use the spare
rocker arm assembly and a spare push rod.  Nice thinking but, well, the
rocker arm and push rod assemblies are sort of the same, but different.
Have a look here:

My question is, do you think I can just use the whole rocker are assembly
and replace all the push rods with these springy things in my '52 A90?  The
rocker arm with the floating tips is beautifully manufactured and operates
very similarly to a rolling rocker - the tips serve to remove any lateral
stress on the valve itself.  I am inclined to use the whole assembly as
is, but I was wondering if anyone knows of any reason not to use this set
up?  The only downside I can see is the thing looks more difficult to
adjust.

I would really prefer not to have to find a complete rocker somewhere else,
since I already have this perfectly good one, eventhough it's a little
different!

Thoughts?
