i don't know how to test the compression, but i've just rebuild it and i think it's a 7.3:1 , but i'm looking for a 1600dualport engines this days and i think it will accept more than a 1300...
i'v been told that the rockers will give a 1300cc single port a gain of 6% in avg, and the dual port will jump to around 12% with fine tuning...
but i'm not so sure of this(still researching this field), any more ideas guys???
