Which head gaskets??
I was told to do a Cometic 4.040 at .036 but i thought you couldnt use a Cometic unless your block was freshly machined which mine isn't with 5k worth or driving on it but the heads will be fresh.
I just dont want to put 15lbs or more to this engine and **** a head gasket..
Any thoughts?
Thanks
