Why do you want to spread it to 130mm? Just leave it at 126mm. Depending on which hub you plan to use, there are different ways to narrow the hubs to 126mm.
Speaking for myself, I will never buy a frame that has been tweaked by some rando with a 2X4 on their garage floor. Do not do this to anything other than a throw-away frame that has no value to anyone.
