Engine build question

Ok ive had a look and cant find anything covering this question guys.
I dont know weather this is possible or not but ive looked at the engines and they seem to be the same size.
What i want to do is take the block from a 7AFE and match it with the 4AGE head. Now looking at the specs of both theoreticaly the only difference between the 4AFE and 7AFE is the capacity.
what got me thinking was looking at the figures the 7A gets about 10 more KW over the 4AFE, so in theory if you put the GE head on then you could pull around 110-115KW out of it before any extra goodies are added, then there will be the extra tourqe aswell. Naturaly if you do it you will do other stuff to it to.
This is just a thought that i came up with, dont know if it is
possible. any thoughts?

i hate to be the one to say it 
but yes this has been done a fair few times before (not as many as 4AG into AE82 or AE86 tho  )
there are a few writeups around the net that you can search for.
rods and crank are supposed to be weaker. porsche timing belt (theres another one that is one tooth less?? )

Ray Halls turbocharging did this with a 20v head and turbo'd it as well. They put it in an AW11.
