My new to me ’56 willys, with a 134 F Head engine, came to me without a oil filter, It appears the bracket I need to install a filter attaches under a head bolt. I’m a little concerned about removing a head bolt just to install a bracket to hold the oil filter attach bracket, for fear of starting a head gasket leak.

So, my question is, Is this a legitimate concern, or a non-issue? Is there anything else I should be thinking about, in regards to installing a oil filter assembly?
Thanks for any advice or help!
