Good choice on the heads.
My recommendation; Use the swivel ball adjuster instead of the elephant foot when using a 1.25 rocket. The reason being, you will run out of travel on the elephant foot and damage it with the increased valve lift.
Second, I also recommend running a little more compression. The combustion chamber of the panchito is well designed and the head runs cool. You should be able to run 9-1 compression with mid grade fuel, Although I recommend premium on any engine I build.
If you wanted to take it a step further, get the chambers CNC machined to 61cc and then fly cut to 9-1. You will see even more power due to the unshrouding effect of the intake valve. When I designed the panchito chamber, I had to make it fit a standard 85.5mm bore. Unshrouding it increases intake flow 7-8 cfm, about 7 horsepower.
