These are G36 cylinder heads from ZCI, they are of the locking block front style which if your gearbox has this shape will work well. Please check your GB first to make sure it is compatible, some GBs may lack the space for this block. It's machined from aluminum and features double O-rings and a nice thick rubber impact bumper. These come in two colors as shown.
Note: The impact pads on these are not always glued on well enough so if you aren't replacing it with a Sorbo Pad (I would recommend the Sorbo Pad instead) it would be safest to reglue the pad on with some CA after better surface prep on the rubber and aluminum.
