Anyone running 545 lift cam with EQ heads and stock bottom end?

I'm running Hughes 1110 springs and retainers but not sure if it's the "new" ones you are talking about. Put this engine together 3 or 4 years ago.

IIRC, the retainers were actually stock for the 4. something motor.
The way to tell is if you can see the bottom of the locks sticking down below the retainers around the valve stem.
