The thing of it is, once the heads are off, you've essentially got the entire top end apart. You only have to lift the cylinders off and unclip the wrist pins and the pistons are out too. Another 10 minutes if you go real slow. It's not a question of time or effort, only if you want to spend the money on new pistons and having your jugs bored.

Ive been real happy with the 555 but was planning on going to 107 down the road but have decided o just do the heads next. Nw when the top end starts to show signs of wear then ill go to 107".

Already have a 103, I'd go with the heads.

The extra 4 cubes won't make near as much difference as some porting and increased compression.
