you can do it in stages, but the question remains why? if the pistons and stroke result in less than abt 10.5:1 compression, you dont need it. if compression is higher, then you do. its kind of binary. if you are going to change your compression later then everything will be apart again anyway so id leave it to later.

if you are going to boost later then your compression now likely needs to be so low that it will be a dog but you wont need the second plugs and you can do it in stages.
