Hey all U torqueHEADS...
I've got a set of extremely rare FEULING "CENTERFIRE" HEADS FOR 454/BB CHEVY - FOR SALE, and mine are serial # 1 & 2...
FEULING "CENTERFIRE" HEADS FOR 454/BB CHEVY - complete original kit with Feuling camshaft and all original accessories including new gasket set... This pair of heads are "Serial # 1 & 2", the very first set available to the public, purchased in February, 1998 thru "Klein Research & Development", the only original Feuling authorized dealer. Tom Klein recently sold a set of these heads for $100,000! Jim Feuling & Tom @ Klein were very interested in my particular application and stayed in contact with me throughout the installation and "dialing in" process, since I put them on my new 1997 DONZI 22ZX speedboat... we tried many different prop pitches, both 3 & 4 blade until finding the best performance with a 4 blade Bravo 25 pitch... adding just these heads alone added 9 MPH over stock... it originally ran 58 MPH @ 4,800 RPM, and then 67 MPH @ 4,200 RPM with these heads, and no other changes. We chose the prop to max the RPM @ 4,200 because that is where these heads have their peak horsepower and torque on the dyno reports, so of course these heads never saw use above that except during prop selection we tried a lower pitch at 4,400 RPM but lost 1.5 MPH at top speed but did accelerate quicker... and speaking of that, you can't imagine how much faster my Donzi accelerated with these heads over stock! Unbelievable, I tell you!.. Even other pistonhead boaters couldn't believe how quickly I'd pull away from them. Maybe they'd get me at top end with their twin big blocks, but I'd blow them away anywhere from a standing start, all the way to my top speed, then if they had more left, they'd finally catch and pass me. According to dyno tests reports provided for a stock 454, these heads add 80 HP & 80 ft.lbs. of torque @ 2,250 RPM, and add 100 HP & 100 ft.lbs. of torque @ 2,750 RPM, unheard of from any other head design in existence even today!.. Typically, you'll only see HP & torque gains in the 4,000 to 6,500 RPM range but will remain nearly the same as stock or even lower in the 2,000 to 4,000 RPM range that you'll normally be using on the streets... Imagine having that extra 100 HP/torque in that low usable RPM range. I just spoke with Tom Klein in March, 2011, and he told me that they put a set of these heads on a 572 with Hilborn injection and it made an unheard of 800 ft. lbs. of torque at only 2,000 RPM!!
According to two magazine articles I still have and can provide to anyone interested, six pages in "April, 1997 Popular Hot Rodding", and 4 pages in "February, 1998 Vette" magazines tell all the incredible details of the ground breaking engineering that went into the R & D of these Centerfire heads made of A356 aluminum heat treated to T56... features much smaller than stock intake & exhaust valves that are "curvilinear" rounded seats as opposed to multiple angled seats common to most other designs... 84 cc "figure 8" combustion chambers that raise compression by 2 - a stock 8.5:1 ratio becomes 10.5:1 just by bolting on these heads... the spark plugs install thru the valve cover with the electrode tip being directly in the center top of the combustion chamber centered between the valves... and the valve heads are within a couple degrees of being parallel with the top of the piston, so no relief cuts in the pistons are needed... Feuling's design takes full advantage of extremely fast gas speeds that allow for more complete combustion, and lower temperatures, all with allowing you to burn 87 octane with no pinging, and BEST OF ALL, THESE HEADS ARE 19% MORE FUEL EFFICIENT THAN STOCK in their dyno testing!! Jim Feuling was recognized as one of the leading automotive engineering geniuses... check him out:

These heads have been on my Donzi from the summer of 1998 until now, I decided to move into a larger boat so we put the stock heads back on and the Donzi's now for sale also. The heads while on the Donzi's 454 logged only 56 hours on the hour-meter, and mostly saw a cruising RPM around 3,200 so they're near new, the only cosmetic flaws are some slight pitting on the aluminum valve covers that is common with aging... I'll get some photos of everything ready for anyone interested. My heads will be available near the end of March, 2011. (We're in the process of removing everything from my boat).
By the way, someone on the forum at: "http://www.454ss.com/cgi-bin/forum/YaBB.pl?num=1239328365/0" posted photos of a set of these heads that were for sale a couple years ago. Click on the "NATC" link below to see some pretty good pics of what they look like inside & out.
