Excessive gas pressure and (or) too much primary air are the main causes.
Make sure gas pressure is correct and reduce it as needed to minimum (allowed) flow pressure while all other appliances are in operation. This should be done as long as this minimum pressure is acceptable for the other appliances. Then check to see what the flow pressure is with no OTHER appliances running except this one. If it is excessive then the gas piping may be undersized.
Then this would be the main problem and all other remedies would be a band aid.
If gas pressure has been set to an acceptable pressure then adjust the primary air at the burner for acceptable combustion without yellow tipping(natural gas) or excessive yellow tipping (propane gas).
Any flame lifting off the burner ports or excessive noise (roaring or whistling) should be able to reduce by reducing primary air with the burner shutter.

And first make sure the orifice(s) are correctly sized and burner(s) are correct for appliance and no cracks or defects in burner and burner is clean.
Get rid of your old Peerless 660 boiler and install a SlantFin of Buderus.:)
