Vavle spring tool HELP
hey all,
i'm in the middle of swapping out my vavle springs.. i ordered the proform dual valve spring tool (67605) and it doesnt work.. the allen bolts are too short and even if i used the stock rocker bolts, the whole unit seems too tall once installed to compress the spring.. after contacting Proform, they said i have an LS3/7/9 tool.. i've read on the forum that many ppl used this tool to swap out their springs.. if anyone has used this tool with success, plz let me know..
thanks
Vinnie

You must be doing something wrong because that's the one I used. Did you take all the rockers off before you started? There is a piece between the rockers and the head that needs to come off.

Ya one cyl. at a time won't work. You'll see why. I used air to hold up the valves. Once the rockers are off all the valves will seat and hold pressure. I am sure 80 psi is fine but I just ran straight from the compressor at 120 psi. It'll shove the piston down in most cases but it doesn't matter. Keep the rockers in order if you aren't doing anything else.

If you mean the one under the rockers, it's a strip of metal about 3/4" wide and the length of the head which you can't miss once all the rockers are removed. Poke around with your search engine for valve springs and look at the differences in the pictures. Or I might (if I remember) see if there's a pic of it in my manual tomorrow.
