Running an engine at high rpm’s for extended periods of time will result in decreased fuel efficiency and increased wear on engine components. Tell ing someone to go ahead and run your engine at 6g's for hours isn't the best advice... Drive it like there's an egg under your foot!

Well yah!  
(but these motors have no trouble running higher RPMs)

You must have an 8V, I've known a good few people with 16Vs that have suffered cracked heads and blocks.

I believe so it probably because the 16V makes around 18% more power so theres a lot more heat and stress. I' just guessing though - I've just never heard of it happening to an 8V

That's odd.  I run my 16's to 5500 ALL the time, and 6000 fairly often, and have had no problems.

These engines are made for the high RPM's, stock from the factory.

I remember when the Chevets came out with their 4 cyl.  People thought that they were asking to much out of the 4 cyl. and they would never last.

I've know people with over 300,000 miles on them and they keep going.

And one more thing too that no one mentioned yet.  It's gas milage.   Now, I have a newer 2.0 16v, but I found that if I go light on the throttle and short shift it ( before 3,000 rpms, it'll only get 24 or 25 mpg.  Now if I still go easy on the throttle and run it up to 3500 to 4000 rpms, and every time I hit a good sized hill drop it down a gear also to just let the motor rev I'll get 28.  It likes to rev, not lug, now, I don't know about the 1.8's but anything below 2000 rpms it feels like it's lugging, and just doesn't want to be there, even the tranny groans until I downshift.    Oh well, anyway , just my .02 ;D

i noticed this this weekend in my 8 valve, i would rev the engine higher when i was driving and i noticed better fuel milage

my lug nuts require more torque then my engine makes ;)

Your best fuel milage is going
to be at the peak torque RPM

These engines have a high RPM
peak torque band.

so which would be the best rpm to shift at for fuel milage reasons?
