Hello all Merry Christmas , I have a silly question , have a rebuilt 440 but was rebuilt about 6 years ago and never fired , used the Chrysler steel head gaskets at that time , since it was not fired for all those years .. I tore it down cleaned and recheck everything, My Question is can I reuse the steel head gaskets over again since the motor was never run ???? It is just a stock compression 68 440 mild cam 470 lift nothing fancy , I know the head gaskets compress when torqued are theses a throw away and use new ???? Thanks
