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

I had to get the special retainers and new 1110 springs to run .515 with plenty of room on the EQ heads and apparently the new retainers and springs allow up to about .580
Otherwise you have to get longer valves and springs or cut the guides down.
I say .580 because the consensus via Clearwater/Odessa they are capable of about .600 with the Hughes spring/retainers set and I like to shoot for plenty of room.

(All stock bottom end and pistons here also)
