This is what I would do!
Talk to your friends a little more, they should know that there is a lot more to stroking a motor than adding longer rods.
You are pushing the piston further up into the quench area and you will need pistons that have valve reliefs so you don't have piston/valve contact. There are a lot of measurments to be taken before throwing in longer rods.
