lower compression?

[68chargerboy]

hi i was wondering if there is a way i could lower the comp. on my motor.  i have the stock cast closed chamber heads 75-78 cc and will run 11.99 comp.  i want to lower it for pump gas but dont want to take out pistons.  is there a way i can do this without new heads or pistons.  it is also a daily drive.  and i plan to get 88cc eddys later but cant afford right now. thanks

Open chamber head with a thicker head gasket will work.
