Goki reed adapter

Hey guy looking to see if a Goki reed adapter is worth buying and if it actually add a noticeable amount of power found one for 350 bucks with new reeds and a 650 intake manifold. Any info would be great thanks.
 
if you want to keep a 550 engine in it,yes they work well but you will need to port the cylinder and cut pistons following their instructions.
if you want to go fast,a 650/701/750 mod is better.
