Depending how/where the engine has been stored and for long, it's possible the compression ring/s have sized in the piston groves. 135 is low but the fact they're all pretty much the same it's a very good chance it the above mentioned.
To sort this you've got 3 options, 1 just run the engine and fingers crossed they'll free themselves, 2 add some diesel/paraffin let it soak for a day or two then run the engine, 3 strip it, while you're in there lap the valves.
