Main differences 4.0 pre 1999 and pst 2000 block

So,

Since I have 2000 block in my TJ with 0331 head and replacement blocks in that age are scarce - I just bought 1994 HO 4.0 engine.

Before I go too far with the build - I t would be really nice to know what problems I will encounter when I am going to replace my '2000 TJ engine (perfectly running, also head not cracked yet :-)

Well, tok the WJ engine out of the junker, has the 7140 head casting.


Block casting is 53008405

Can I use this in a 1999/2000 TJ or should I be better of just reusing the HO head?
