given a turbo kit running ~11lbs on a stock motor with a 3mm headgasket...

i can add boost to make more power (adding stress to the motor)...

i can also gain power by doing headwork or getting an equal length turbo manifold... both of these add power without adding boost due to better flow and efficiency...

my question is will doing either of these things to gain (lets say 30HP) result in the same amount of overall stress to the motor as adding boost to gain 30HP without doing any of this other work?

I think you might have a hard time getting 30hp out of those mods, but stress is stress. Its just that its stress in different locations and parts.

Example, better headers/exhaust make hp by allowing the exhaust to flow better (not much maybe, but its an example). This can reduce stress on some parts and won't effect the engine, but at the same time the added hp adds stress to the clutch/trans/diff.

But to make it short, anything that allows air to move more efficiently is good. Restiction is bad. Shouldn't hurt the engine at all unless the tune is bad, might burn your clutch out quicker though!

thanks... i used 30hp as just an ex. like with the alaniz headwork... knew about the drivetrain... but that has to take the power regardless... was wonderin specifically about the motor and if headwork was a wise investment for gaining power and prolonging the motor instead of just adding boost...

I can't see why it would hurt anything unless the shop doing the work was a complete screw up. If you're running a turbo you'll probably need to go back to the dyno.
