The brake check valve creates a vaccumm inside the engine, maybe not as strong as plumbing it into the exhaust, but a vaccumm.
On the two nipple breathers, some had one side plugged with a solid plug on one side and a plug with a small hole in the other. So plugging one side and hooking a brake check valve will work fine. Maybe get a one nipple breather and use that instead, it will bolt right on.
