So why NOT aluminum heads from a lumina? The heads will bolt on to the 3.4l V6(a very common swap because they are easier to find than the 2.8 if you need a new engine). The intake from the lumina and injectors should all plug in. These swaps are common enough on the S10 forums(and not unheard of on the f-body forums). I know you need to put the pistons from a FWD 3400 in to lower the compression ratio. But why is this not a common enough mod for the fieros? What am I missing?
Exactly, in fact I'll be taking a 3400, and putting the iron heads and Fiero intake on, it may be restrictive, but it is unique and really suits the car.
The Lumina engine is a Gen II design and as such has the splayed pushrods that the earlier engines do not. I can't imagine that being a direct bolt-on.

All GM 2.8 engines and their successors use parallel lifter bores.
In a splayed-pushrod engine, the lifters are straight, but the pushrods are crooked.
The pushrods operate crooked in the socket of the lifter.
If it doesn't have to look "stock", you'll be waaaay ahead of the game by just swapping in a 3400 or 3500 - or even a 3900 - and do the necessary ECM swap, fabrication, and wiring to accommodate. This is a very common swap within the Fiero community. Tons of documentation is out there. (I lust after a 3900, but have too much stuff going on, just now, to make it happen.)

Those are my thoughts as well. Why try to reinvent the wheel when there are many proven solutions out there to power improvement. The LZ9 3900 V6 engine will provide 240 hp and 240 lb⋅ft (325 N⋅m) of torque stock. That's what the supercharged 3800SC series II engines provided but the 3900 has an amazing flat torque curve all the way out to the redline. Lots of swaps have been done with that engine.
