I know i would have to window it for my gt80 reeds.

i beleve that these are pistons that have been lightened,not windowed,i also beleve that the holes drilled in it would weaken it if you did a proper window.try apollo motors for a windowed piston

That's what I was thinking the small hole's for added oiling should only be on the exhaust side so the intake side could have a proper window
