just did a compression test
1 cyliner 150
2 cyliner 150
3 cyliner 90
4 cyliner 150
So not good theres no knocks/bangs so could be the head. A burned valve or something?
i got a spare 1300, what will happen if i put the 1300 head on the 1600 block? will it raise compression or make it worst?
or am i better off putting the 1300 in now and striping the 1600?
