I had one of the very first 3850 display heads from SEMA 2007 or something, sold it to a fellow awhile back.

It was just an exercise in moving the pushrods around to get them out of the intake ports, just addressing
normal small block performance issues.

It was meant to do battle with the head referred to as Indybrock. It's an Edelbrock head with pushrod pinch completely removed,
straight line of sight intake port.

There was also prototype "in between" head which was the same Edelbrock casting + relocated the intake pushrod slightly, but not quite as far as the
3850, and it had some of the pinch is still intact. I still have that one holding down a shelf and would like to get rid of it.
