Can i run both grounds for these couls to the same place? I dont have a signal ground back to the ecu and would like to ground them both at the engine.

Perhaps some filter caps would be ok?

fge,

You are supposed to ground them at the block. See: http://www.useasydocs.com/details/coils.htm and especially this illustration:
