So in my search to find a new motor for my 03 OZ iv been looking at the 4g64 sohc 16 valve 2.4. But can't seem to grab one anywhere. But iv found hundreds of the 24 valve version. My plan is to do the evo head swap onto to 4g64 block but I don't know If the blocks are the same

Are they?
If no? Major differences?
I I know the head swap works on the 24 valve but I don't know if the block will fit the same in my bay. Anything you know could help. Thanks

 

Anybody?
