Does anyone know if the headers will fit X- or J - heads? Abd will the transmission parts work with a 833 OD in a car?

The headers should fit those heads as people are using LA headers on Magnum heads(including myself).

I believe the Magnums use an 11 inch clutch, and there may not be a small block bell housing that will work with it and your OD 4 spd.
