New to building. Just wondering if the jp speed hammers are interchangeable with stock ar hammers from say a dpms LPK?

Yes they are.

You can also neuter the stock hammer and save money.  All you need is a dremel!

Really? Is there directions on that?

Check this thread out.  I bobbed one hammer and got a JP spring kit.  Haven't tried it out yet.  I intend for it to go with my rimfire upper. We'll see if it has the ooomph to fire those primers.

I have the yellow no spring kit and I modified my hammer.  It has fired everything so far, including .22

This plus JP springs made a nice difference for me.

I too, have dremel-lightened my stock hammer and use JP yellow springs, and thus far have fired 260rds of M855 without any problems.
