yes if u degree ur stage 1 cams, you will see slightly more hp.. stage 1's dont NEED to be degreed as long as you keep the gear and chain lined up during the install... it is recommended though.. with stage 2 and up, u do have to degree and with stage 2, the difference with no other mods is probably about 7-10 hp and depends on if the stage 1s where degreed etc, but with stage 2's like said earlier u do need springs, u will need steeper gears because the stage 2's loose power down low, but however if u do plan on doing more stuff, stage 2's will net u considerably more power than stage 1's when/ if u port ur heads..
i actually made a thread about cams probably 5 days ago.. in talk.
the problem that i am having, i am not sure if u want to do the install urself, or if u have tons of money... but i was quoted about 1500 for the install... because a shop wants to make sure the install is correct and the cams are degreed so u dont get any ptv contact...so basically i would check around in ur area if u are planning on getting them installed somewhere, and see how much the install can be because if its about 600 for the cams, 600 for the tune, and 1500 for the labor... u might as well just get a blower..
