I copied this from 50 tech.com
You need mass air to do heads cam intake.
Mike Hudson - Something about 114* lobe separation, and some critical timeing of durations... beyond me really, buy Bob Cosby and Ed H. have gone into the 11's with worked over stock heads, intakes, and fancy cams with SD. Many other run H/C/I with SD in daily drivers. Members of 5.0 Tech forums also know otherwise.
That cam wil most likely cause your engine to surge. Go custom or try to find a cam with at least 114 degrees of lobe separation.

A cam I've been considering is the steeda #19 cam because its lobe separation is 115 degrees.
your main concearn is not absolute performance or sound when it comes to adding a cam to an SD car. the problem comes with the drivability related issues...like nasty surging, hanging idle, constant surge dying, generally creating a headache of a car to drive. I drove a car like this until I did my conversion...well tried to, tired to tune it, tried to bear it...but I just was a PITA to drive. Like too many people on here your putting to much faith in the idea of a cam and forgetting how little return you actually get from it, especially with stock heads. My opinion is to get some good heads and do that first...that you will feel and the car will infact sound better (better volume flow, you'd be surprised) and collect the mass air conversion parts while finding a good cam swap to do at the same time.
look at the crower 15511 its a split duration cam that favors exhaust side ...

many people have had great luck with it and i just had one put in my set up but havent started it yet ...

performer heads
crower 15511 cam w/1.6 rockers
porter performer intake ... and full bolts on's ...

chances are i will never swap to mass air ..... my car idles fine and gets 17mpg...... its a c4 car so i have no overdrive .....

i couldnt be happier id say go crower
