Big Valve X Heads on Low Comp 72 340

Looking at possibly putting a set of 2.02 X heads on my 72 340 . It is bone stock cast crank low compression factory cast iron intake factory exhaust manifolds 600 Edelbrock factory torque converter 904 auto I recently put a set of 3:73 gears in it . Just curious if I will feel any HP gains adding the X Heads with a thinner head gasket . Will the “ Juice be Worth the Squeeze “ . No future plans on rebuilding the bottom end she runs strong may consider a good set of headers down the road but I’m pretty happy with the factory cast iron exhaust manifolds for now .
