Are they 100% the same?

Are the 3.0 FWD heads exactly the same as the heads they put on the TTA's...specifically the valves and seals? I'm getting a set of FWD heads to have ported and am concerned if I need to upgrade the valves/seals. As it is I'm sure I need to replace the springs, anything else???

the 7515 will bolt up and work the same.

Forget bout looking for 6702's. As far as whats needed, take them to your porter, have them mag'd, new guides, bigger valves, ported, new seals, new springs, etc..

Actually send them to Champion have them do theyre majic.

Thats another option. And if heads came off of different motors, CC the combustion chambers.

Ohh and yes get them surfaced.
