Those are not GEN1 heads. Look at the angle of the valve covers, they're almost vertical. Also, the height of the intake manifold interface to the head is a dead giveaway that these are gen II or later.

I thought the same as you Jazzyjeff but according to the builder they are gen1 heads. This pic was taken about 20 years ago. Before Gen2 heads were even built by GM
Those intakes only fit gen1 heads also. They didnt build a special one off intake for these heads.
Even if they are gen2 heads, that doesnt change much. Gen2 heads are a dime a set.

Those are not Gen I heads. They have equally spaced exhaust ports and the valve covers are Gen II. Nice intakes. The front manifold could be refabbed to fit the Fiero. If you wanted it badly enough...

Anyone want more info? Obviously wont fit a fiero with those turbo manifolds. Documented 750hp out of a 2.8L
dont you guys think those exhaust manifolds could be bent in such a way as to allow clearance in the fiero engine bay? as to the height of the motor, im sure a custom rear lid could be fabricated

The builder is wrong, those are most definitely not Gen1 heads.

Forget reworking the manifolds, Ill chop a slot in the firewall, and sit with the seat all the way up if It would mean I could get that engine in there. lol
If you can find those heads and that intake, you could get the same power and response with a larger single turbo, right over the transmission. Then, your exhaust manifold problem is fixed, and you just have to worry about the intake --Bryson

This may not relate to the engine pictured, but the RFRE on the valve cover got me searching. I found this over on clubcobra.com, subject was "Want to be different? 1000+hp twin turbo V6 motor.... "
"Here's one out of left field - a Ryan Falconer built V6 Chev with RFRE ported 18 degree alum heads, billet crank, Carillo rods, JE pistons, inconel & titanium valves, cast alum sump with integral mains, billet front drive plate and mounts, roller camshaft, Cosworth Engineering slimline oil and water pump, twin Garrett turbos, Kinsler intake, Motec M8 management system with expanded dataloging capability, exhaust, dry sump tank, spare turbo, etc.
This motor cost Opel $40,000 to buy from Ryan Falconer Racing Engines. They sold this unused short block for $25,000. Ryan then fitted his modified 18 degree heads complete with his own stainless rocker arms, Kinsler injection manifold and Motec M8 computer. First time on the dyno with the smaller exhaust housings, the motor made 893hp and 639lb/ft. The larger exhaust housings allow this motor to make around the 1100hp mark on alcohol.
Summit Motorsports in Brisbane, Australia paid RFRE $25K for the basic motor, then spent a further $30,000- on extras. The turbos are worth $3,300 each, and there's an unused spare included. The Cosworth pump cost $9,000!!!! The exhaust system was $5,500-, then the Motec, dry sump tank, a couple of thousand dollars for all the braided hose and fittings, then the (not inconsiderable) labour charge for Ryan's services.....
This was fitted into a racecar for ONE DAY in the States to verify the working order of the motor after the dyno runs, and to gain some dataloging in "real world" conditions. All of this datalogging is available for any interested parties. The motor was then shipped to Australia and fitted into a racecar. After overpowering the chassis and generally being frowned upon for lifting the stakes too high, the style of engine was "actively discouraged" from competing in any further series and has sat in the corner of a race shop under covers since.
The motor is offered for a total price of $30,000 which includes all the spares. Unless you want to blow the Run and Gun guys out of the water, I wouldn't expect this motor is destined for a Cobra I imagine some of you guys would also dabble in some dedicated roadrace cars, and this might just be the ticket to the winners circle!"
That begs the question... What can someone do to a stock 60* fiero motor to hold even 1/2 that horsepower? I didn't think there was much of an aftermarket for the 2.8 other than a couple cams and some misc bolton stuff? 3.4s have a little market tho.

Well, virtually ANYTHING is available if you want to throw enough money at suppliers which is what happened in this case. There's a world of difference in the resources of a real race team and what you and I might have, or want, to expend at a project like this. The big things would be to come up with the forged crank and good rods. Pistons are not that tough, most major manufacturers will forge and grind you most anything you want them to make. Heads are also a matter of money is you're willing to let someone like AFR have a free hand at them, but then you're looking at mega bucks as well.
Same now as it was 50 years ago or longer. Speed costs, how fast do you want to go?

moooooooooooooooooost definately! I was just a little curious. We've pushed a 3.4 to well nearly 400hp with a stock bottom end and it still drives to this day. But I've always heard the 2.8s are 1/4 the engine the 3.4 is. I'm going to turbo mine this weekend I think and was a little curious on how much it will hold for a while. I think I'll run ~8psi or so and play with some different injectors and fuel pressures.
A few years ago I was talking to a guy at work about Fieros and v6's, how I'd like to build one. He said someone he knows was trying to sell him a couple all aluminum 60 degree v6 race engines(he's a circle track racer). I would love to get one to "detune" for street use.
