I'm going to be testing how much space my valves have with my 155 kit. Putting play doh in the pockets, spinning the engine over, and checking how much space i have between the valves and top of the piston by how much the play doh is squisued. Bought pink to match the red on the scoot (I couldnt find red, and orange was treacherous lol). Plus, if all goes to shit and the play doh ends up smeared all over the walls, itll be a pretty color.

Anyone know how much space is recommended between the piston and valves? Im using some NCY performance springs to lower the chance of valve float, but i was looking for a safe margin and can find literally nothing online
