Those heads are more of designed for naturally aspirated as noted by the compression ratio. The stage 3 comes with the rockers. If you were to get the Stage 3 head, lower compression pistons, and break $240 for a cam - you'd have an animal.

Im not really looking to put that much power through that transmission. I could probly eventually afford to build up the motor but not the transmission too. What kind of a gain could i expect from the dampener, the 62 cam and the rockers?

Its hard to say because nobody has done it. I'm not sure what ratio they used to rate the cams valve lift, but if they used 1.5 (generally) then with the rockers you'll have a total valve lift of .504". Should get you moving quite well considering stock is somewhere around .400" with 1.6 rockers. As far as the dampener, I have no idea. ehhh...35-45hp? Again though, I really don't know.

I am very interested in doing the rockers, yet would I have to do cams as well. Also, can someone give me an idea of what kind of job it is to 1.) do the cam job, 2) do the rockers, and 3) do both at once.

Also, can I do just the rockers? Thanks.

You dont have to buy a cam with the rockers, one isnt always neccessary to use the other. I can see the cam being a fairly extensive install, however the rockers should be simple

Well, if you can do one without the other, then I would probably be in for the rockers this spring. That is when the next group was buying right? Let me know.
