11/32 valves in X heads

360, I've used them before for both cost and the smaller stems. Truthfully they are all the same price now when you're looking at lower cost performance lines... But Magnum stuff they get used in. If your valve stem heights are off even tho the seats are correctly placed, you can cut the stems. You just have be aware of the lock and where the retainer ends up. Meaning you can't whack a ton off...lol
