Is my piston falling down so much?

[LUISFER764]

I installed a +4 crank in my blaster, so i put a 2mm spacer in the cylinder base, but the piston gets down 5mm from the transfer ports

if its not ported to match the longer stroke, all your port timings will be off, therfore not running to fullest potential

do you have pictures of the matched ports?
