Rocker arms

I have been looking into getting aftermarket rocker arm. Does anyone know what the stock rocker arm (ratio?) is? I assume they are 1.5. I've read that if you put 1.6 it's good for 10 hp. To me that's a pretty cheap mod with a preety good gain. Let me know what you guy's think.

Go 1.8's, SLP sells them and they are very nice pieces... I'm starring at them right now! (for another customer)

Sounds good. One question; will I have to replace my push rods or lifters? Thanks for your help

If you do the rockers, no, the only thing I would recommend is replacing the valve springs to something that can take the added stress, problem is, once you do both you can buy a cam cheaper.

Thanks, what type of springs would work best?

Stock is 1.7 ratio, according to SLP's web site

All lot less money would be to use the LS7 1.8 ratio exhaust rocker. Something like $144.XX + Tax + Shipping for a set of sixteen. p/n 12579617

And LS2 GTOs have LS6 type springs. Good for the additonal lift the 1.8s would supply.

All you need are the rocker arms.

With that part number I assume they are GM parts? Thanks for the info, I will look into them.
