I just ordered a 7.62 conversion, I have the old gas system on my XCR, do I need to order a new piston head to go with the conversion??

Yes, you will need a conversion when you want to switch back and shoot 5.56. Might as well order it now so it is ready when the conversion is ready.

thanks man. i too was wondering the same thing.
I failed to order one with my 6.8 conversion and had to wait until it came to shoot 5.56 again...
I have my old gas valve for sale if anyone doesn't want to switch over to the new. I don't know if RA will sell a conversion without a gas block, but I'll sell my original for cheaper than a new one (duh).
I've got a spare old style gas block and piston head since I updated. I'll trade it for a couple of 1/2" peel washers or crush washers.
Wait a second, do I need to order something else along with my conversion kit to make it work with my existing XCR??? ??? ??? ???
as long as you have the new piston screwed on, you can switch the new gas block that comes on the kit barrel with your old barrel. depends on how often you are going to be switching out. if you will be changing calibers frequently, you may want to order and extra gas block. if not, you shouldn't worry too much about it.
I just got off the phone with Ty,and according to him you get a gas block when you order a conversion kit.
Yep. you get one put on the barrel already.

The issue is if you had one of the old style gas blocks and ordered a conversion kit the kit comes with the new gas block. The piston heads are different because the two types of gas blocks are different. If you have a newer style rifle with the new gas block, you already have the new piston head and will not have an issue.

If you have the older style gas block and the newer conversion kit, you will just need to unscrew the piston head from the operating rod and replace by screwing on the new piston head. Not a problem, just takes a little extra time and the need to keep track of the odd piston head that's not currently on the weapon.
