Good onya, when my 4age shat itself, I put a dodgy 7age together for $400.00, thats for everything. Handled a 100km per day commute for months, absoloutely no dramas in the AE82, now its going into a TE71 shell, and I fully expect it will last a good while before shitting itself. The only concession I made in driving is sticking to a 6000 rpm rev limit (standard bottom end). From a mount point of view the 7afe block is all but identical mount wise to a 4age, the only difference being block height. So yes, it will sit 15mm higher in your engine bay, all other things being equal.
