KW/torque gains from roller rockers / cam?

[pillzor]

anyone know what type of power figures i could expect from either of these 2 , i know theres different ratio rockers and different cams but thats as far as im educated on them so far :P
car has cai/ delcowizzid tune / stage 1.5 shift kit / extractors and a 2.5 inch catback exhaust and its an ecotec with 205 on the clock.
so im deciding whats next on my list of upgrades so any suggestions would be appreciated ( yes i know get a v8 but thats not what im working with here )

personally i wouldnt put roller rockers on ur old ecotec,
increased compression means more of a workload for the engine.
if its not in really good nick your engine wont last as long as it would without...

go roller rockers and cam, should see a few kw gains...there was a bloke on here that only put a cam in his ecotech and he got in the high 120rwkw's, dunno how big the cam was, but you could hear it when it was untuned, i havent seen it in a while and its since been tuned so might sound a tad different

Skip the rockers, just get a big cam in it and good springs, with the ecotec go one cam bigger than you think you want, then go one bigger again

what type of gains do you think id be looking at and what type of money?

see the cost of the cam is quite small, its installation which is the killer. remember a cam by itself aint gonna get u the figures u where hoping, get compression upped as well. the more rwkw u want, the more you have to touch, the more u touch the more it costs.. a vicious cycle
