From what I've read the DE head is a little larger than the E block, so it seems the E head would be a little smaller than the DE block.

I have had much discussion with this topic. Conclusion is that the DE head is slightly larger and hence wont fit on the E block. So no you cant just replace the head. You will have to replace the entire engine from the gearbox up (this is what i'm doing) But the gearbox is exactly the same, so you dont need to change ne thing from there down.

Its not as difficult as changeing to a totally different engine (eg. SR20)
