Bill,
Dzus fasteners on the head... I LIKE it... develop it and you will have a lot
of takers for the same reasons you quote below...
I however dont take as many spart parts as you do any more.... I only take
parts for the things I really DONT want to work on... As we all know... the
thing that breaks will be the one you dont have any spares for...

I don't know about you folks, but the head on my racing engines comes on and
off so many times I'm thinking of using some kind of dzus fitting. I can R&R
it in about two hours with some help. Dumb things like pulling out a pushrod
a little too fast, sucking out the follower (once), or breaking a head stud
off during retorquing (once), or gasket leaks (many) have made me an expert
at high-speed head pulling.
For that matter, I carry rod and center main bearings, sleeves and pistons,
spare oil pump, water pump, etc.. I don't pop a beer, I pop the oil pan and
start fixing. Might as well, going to need to fix it anyway. At the track
there's usually someone there to pass the wrenches.

As neat as this sounds, I can't ever imagine wanting to change out a
camshaft in the paddock. If something happened to the cam or a tappet that
wiped out a lobe, the remnants of the calamity are in the engine. I have way
too much invested in engine parts to come to any conclusion other than push
it into the trailer and open a cold one. It's spectator time. Those
big purses we are racing for are not worth trashing expensive bits, IMHO.
;-)
Not to mention that I always thought it is frowned upon to reuse tappets on
different cams.
Now changing out a cam for some back to back pulls on an engine dyno, that
sounds like a worthy cause. But before I put that engine in a race car I
would probably want to refresh the tappets.
Getting impatient waiting for Spring in New England.........
