    I found a great deal on a 6.5TD shortblock and have traded my way into a complete running 6.2 with an aftermarket ATS turbo (missing compressor side of the turbo however), wiring, even an extra diesel cab for parts... So now I want to build a turbo'd motor using the 6.5 block but what about heads and intake off of the 6.2, are they the same as the 6.5 or will I need to hunt down newer heads and intake?

    6.2L heads and intake will work just fine on the 6.5L. However, you may find a slight power increase by using 6.5L turbo heads. No need for a newer intake unless the 6.2L is using a C code EGR intake. If so, getting a later model J intake would be better.
