....I doubt the cylinders are rusty but being under a tarp for 8 years could well do that. it's hard to say.... I suspect you have 160psi in each cylinder and your gauge is just off.... check it on the Triumph real quick if it is about as low then don't worry about it....
....
it's very common to get bad gauges now days for some reason especially if it's a fairly cheap gauge !
....
it could be stuck rings on the piston due to all the oil and stuff you've been squirting in there LOL but it's highly unlikely !
.....
if it was running decent I'd leave it alone till I could confirm exactly what the problem is.
.... if it was firing on both cylinders but not running the best I would suspect the carbs being dirty still.....
....
Don't get led astray by the low compression reading when you don't know if the gauge is accurate..... if it is then yes the head needs to come off.

Bob unless you ever been to alabama it has very high humidity and high temperature and I been thru out the south state in big rigs with my mother ex-boyfriend who long haul driver to florida one summer.
The compression test gauge can be easy be check with against a air compressor gauge usually within + or - a few pounds of being accurate to each other.
