Who knows what evil lurks... :-)

Anyway, I just pulled the receipt from GPR: 2nd oversize 16v pistons,
$325 + shipping ($14).  Maybe they just liked the cut of my jib.

Maybe.  It's really up to you.  Keep an eye on the oil level, put up
with the bit of clatter on start up...

Probably.  Depends on you again.  How fast do you want to go?  Are you
the kind of person that always wonders what it would be like if you
had done "just a little bit more?"

It's not only the pistons, which are made of a material that expands
less so tighter tolerances can be run, it's also in the rings.  If I
was going to be running forged pistons, I wouldn't hesitate to get
totalseal 'gapless' rings.

More is better, can't argue that.  It's going to be a personal call
on your part though.  Just remember, the last %10 probably costs %50,
if you know what I mean. :)

Both, at least that's what my local machine shop is doing.  They make
sure the pistons, rods and all the assorted hardware weigh the same,
the the whole assembly is spun balanced.

I know how you felt, I thought it better to spend like mad now and
enjoy the power for many many years to come.
