Are there any other V6 manifolds/headers that will work on our cars?
"Sprint"-brand headers, which I've had on my Fiero for some time, bolted up just fine to what the 2.8L stock iron exhaust manifolds bolted up to, a 2.8L Fiero engine.
Sprint headers seem to last forever, and without
cracking problems, which the stock iron exhaust manifolds sometimes develop.
Sprint headers for the Fiero's 2.8L V6 are available at The Fiero Store (Their single part number, 95727, covers one pair
of V6 Sprint exhaust manifolds.) Their cost is not inconsequential (at least not for me): $599 U.S., for one pair of two Sprint headers, exclusive of shipping.
However, the price for these headers, unlike that more typical of other exhaust manifolds/headers, already includes their ceramic-coating, for both under-the-decklid heat management and improved header longevity --- an expense which likely makes less sense if you plan to keep your Fiero for only a relatively short period of time.
In any event, that caveat aside, I'm confident that new Sprints should fit your Fiero's pushrod 2.8L or 3.4L V6 with minimal difficulty, as did the Sprint headers from The Fiero Store which I used initially on my daily driver 2.8L Fiero, and then transferred to the swap of a pushrod 3.4L engine into my Fiero near the end of December of 1996 --- an engine (with those same Sprint headers) which I still have in my daily-driver Fiero.
Good luck to you with your "V6 manifolds/headers" project that you mentioned, Idaho Wolverine
