    So I have heard good things about them as far as stock castings go. I need to know what you guys think of them and what cars they came from. Also specs would be good like combustion chamber cc, valve size, intake/exhaust cc.

    I know a guy who knows a guy who's selling a set of Fuelie heads just currious about them.

    with Vortecs available so cheap, fuelie heads are better left to the nostalgia guys. Vortecs have better chambers, better ports, they're fairly new (or brand new if you buy them that way), and dont require any mods to run on unleaded gas. by the time you brought a set of fuelies up to the performance level of Vortecs, you'd be in the price range of a good set of aluminum heads.

    But compared to the smog heads of the 70s and 80s is the Fuelie heads better?

    Also what cars came with Fuelie heads?

    slightly better, will likely need hardened seats to run unleaded, unless changed already

    "Fuelie" came from the fact that they came on 55-65 cars with the rochester mechanical fuel injection(think select vettes, shoeboxes, impalas, ect.)

    the Double hump heads came on many cars. The fuelie version ran 2.02 intakes, and 1.60 exhausts. These were very good heads for the day, even into the 90's. The Vortec heads are probably the best production iron small block head Chevy has put out. If you have a set of double hump heads you can run them without needing to change to hardened seats unless your into the throttle all the time, and put thousands of miles on a year.

    Keep in mind they don't have the accessory bolt holes drilled.

    available in both 1.94/1.50 and 2.02/1.60 combinations, 64cc chambers.

    if you've ever seen a double hump head run on unleaded gas without hardened seats, you'll know its not pretty. the valve will actually beat itself into the head casting, rendering it useless.

    I don't have casting #s, but I did here today that they are off a early 60s Corvette 327 and have 64cc combustion chambers.

    yeah,check the #'s!!!

    ALWAYS check the casting #'s on any heads or engine you are planning to buy!!---many times "fuelie heads" or a "454" Big Block are NOT,they are something similar looking,but not the real McCoy.....only way to be sure is to go by the numbers...

    I saw a "454" advertised at a swap meet once,and I could tell from 15' away it was a 366!!..but to the casual observer,it looks identical..

    I had to convince one guy by looking up his casting numbers at the junkyard,to prove another yard sold him a 366 motor from a school bus,and they insisted it was either a 427 or 454 !!..he paid twice what it was worth!.:doah:..it was a tall deck 366,and had a vacuum controlled govenor built into the distributor..he wondered why it was such a "dog"!!...:rolleyes:

    I've seen "Fuelie Heads" come with angled spark plugs,some versions had straight "normal" plugs too..drilling the holes for the accesory brackets can be difficult and challenging.....there are better heads out there now,as already mentioned...:crazy:

    Checking casting numbers in this situation may not always be good as the fuelie heads used the same casting numbers as the regular old camel hump heads most of the time. ALL fuelie heads had 2.02"/1.60" valve sizes. I've seen many heads over the years and can tell from a first glance if they are true fuelie heads or if someone converted them to 2.02"/1.60" valve sizes. Casting numbers are sometimes over rated and it takes years of knowledge to understand what GM did and you still may never see everything that GM did.

    Agreed over a good amount of mileage or heavy foot usage, but for an offroader it shouldn't be a problem. If its a daily driver, or towing machine an upgrade to hardened seats would be wise.
