Is it worth my time to put a rkt head on my pro I can get one for a good price

What domes are in it? If its for one of his piston kits you will need his pistons also, and possibly spacer plate. A reason the heads are cheap used is they usually require a set of special pistons also.

If it is the standard rktek head, I put one with stock compression domes on my 2015 pro and I did notice a difference and so did my riding buddies who have also ridin my sled before and after the head was installed. the sled also now runs cooler.

It is the the low compression head that works on stock engines

I'm not sure on the stock compression head but the high compression head works well IMHO. But it's the chamber design that might make the difference, it won't be worse most likely run better.
