You can use the 154 pistons, but you have to check the clearance with the stock rods, they may be too long. You should see an increase in power of a couple of horse power if you also go to the larger, later carburetor for the 154. If memory serves, the 154 fielded 12 drawbar horse power and the original was around 9. The pistons will cost about $70 each plus rings and rods (if necessary). I looked at the upgrade on my rebuild, but did not actually get to the point of measuring the rod/piston combo for clearance. Original pistons are flat tops and cast iron, the 154's are round tops and aluminum.
I believe that it is the round top that makes the clearance difference. In any case, the parts manuals I have seen and have call for rods with a different part number on the newer engines.
