Thanks guys I used to have the ratio written down but couldn't find it. Also I thought GX spring height was the same but wanted to be sure............the spring info is in the tech section here, so that's no problem. Maybe we could get the rocker ratio in the tech section as well..........surely some other guy a year from know will want to know.

The GX rockers cary the same part number as all other 1200 models.
The GX's installed spring height should be the same as regular 1200's too.

not sure wether all A series rockers are the same, but most I have seen are 1.44:1

Does anyone know the rocker arm ratio for for A12GX............I seem to recall 1.61 to 1.
Also is the assembled height on the GX valves differant from the standard A12. I'm ordering up a cam and need the info..............(unless one of you guys already have cam specs for a 12-1 compression A12GX that will work with a non close ratio box)
