You would be a lot better off swapping the heads to a set of aluminum like the Edlebrock 88.0 CC Street RPM heads and use the 1009 head gasket twocents
The aluminum heads act like they lower the compression by sucking heat out of the combustion chambers as well as they flow more air making more power with bigger valves scope
BTW, I hate the Mopar cams like the one you have down There are a lot of better grinds out there now so I would change it while it is apart and make that motor run a lot better twocents What year and body style car are you going to run this motor in and what rear gear ratio and rear tire size? work
