Good luck with Muscle Motors! I called 3 times in the beginning of December and I'm still waiting for Mike to call me back.

Just do the predator head , its a way better platform and you might be able to get a set before November if you are lucky.

Well pistons are the part that changes, and you will need to for the PSO as well anyway so I guess I don't see the issues.

Muscle Motors is doing a set for me. I think they do their own CNC porting.

I would be shocked if Muscle Motor did any CNC porting of anything. As far as I know they send everything out... To Modern I think. Correct me if I am wrong, but pretty sure I am not.

Well I have two set both between 475-480 on a number of different benches. One motor is just shy of 1100 at 525" with a fairly small cam. The other we will see hopefully next week. Both sets done by cylinder head specialists(rear non Mopar shops) that started with raw castings. IMO not worth the expense to go to a PSO if you over an MC or B1 for what is a potential of 25ish CFM.
BTW I know I hear it all the time no way those heads flow that much or make that power. But the car seems to run a representative number. I am doing a Predator deal now and will have some numbers eventually. Those heads are at 540-550cfm on the same bench as my MC stuff. We will see what kind of power they make here soon enough.
