Hey guys, I got a CrossFlow Head that I’m going to use on a 200. However, I’ve been advised that I may need Custom Pistons with Valve Pockets to make it work and to get the compression to 10:1 at least. Cox Customs has been a big help so far as well as Bubba. I know the Fordsix Tech Guide doesn’t mention any change to pistons when swapping the Xflow Head, so hopefully one of you guys have some info on Pistons for this particular build. Thank you in advance.
