Any gains adding 1.6 rockers to stock 273?

i love how dude is all: it's just a daily and i don't need a ton of power, i enjoy driving it but a little more pep would be cool.

so everybody immediately goes: 273 is trash, don't spend no money on that and get a 340/360, magnum or even a 318 is better.

because, yeah, spending 3~5 grand is the answer to: i like my car and i enjoy driving it but wish it has just a little more scoot.
Happens every time. It always turns into a maximum horsepower war.
