The head design looks extremely close to the 4.2L Jag I rebuilt about 10 yrs ago. Looks like it has the same dual timing chain/intermediate gear set up with the cam adjustments at each cam gear etc. The Jag was easier to deal with due to iron block. That mother was hugely heavy!! It weighed in about the same as a 440 mopar I was working around the same time.
