If you want true out of the box ready to run you can't go wrong with IMM or Hughes either one.
Odessa Cylinder Head in Texas is a decent source for the basic heads and good prices, but they don't do custom stuff like springs and such as far as I know, and the ones that come on preassembled heads are barely capable.
I did my own springs and hardware as well as a basic inspection stem clearances and valve sealing, new positive stem seals with Hughes Springs and retainers/locks set.
Actually I was fairly impressed with the EQ's right out of the box except for the limitations on lift.
The spring seats and stem guides can be cut easy enough to solve that though.
230 CFM right out of the box ain't bad for the price I think.
I see they are doing the bigger 2.02 intake valves with better springs though.
120 seat pressure and up to .600 lift on the springs and stainless valves.
