Header Selection Info

Postby Bob Gumm » Fri Sep 10, 2010 11:04 pm

There have been a lot of questions regarding header selection. In my opinion, header selection depends on your engines needs and your preferences. I have more info on my web site covering these headers. Also, except for the big-block headers and the Stahl small-block race headers which require rerouting of the steering shaft, all of the headers have one tube (#1) that goes over (around) the steering column. Here is a brief synopsis...

Small-Block Chevy V-8 Headers
Sanderson CC13 (shorty headers)
Specifications: 1-1/2" Primaries with 2-1/2" Collectors
Pros: Very low-cost, no road clearance issues, not too difficult to install, no tubes pass through the fender wells, have a thicker flange (no warping = no leaks). Highest quality!
Cons: Small primaries, steering column must be removed and reinstalled, not a full-length header.
Notes: Best suited for mild engines, available with ceramic coating (recommended). They are so inexpensive that if you bought two sets it would still cost less than almost every header on this list.

Hooker 2135
Specifications: 1-1/2" Primaries with 2-1/2" Collectors (some don't have collectors; you weld the exhaust directly to the header).
Pros: Medium-cost, full-length header, no tubes pass through the fender wells, not too difficult to install.
Cons: Small primaries, possible road clearance issues.
Notes: Best suited for mild engines, add a "0" in front of the part number to accommodate air-injection manifold.

Stahl 124
Specifications: 1-5/8" Primaries with 2-1/2" Collectors
Pros: Medium primaries - great for those high performance needs, unrestricted flow, no tubes pass through the fender wells.
Cons: Very high-cost, car may require modification for clearance, possible road clearance issues.
Notes: Best suited for mild street-strip car if you don't mind the high-cost.

Don Hardy
Specifications: 1-5/8" Primaries with 3" Collectors
Pros: Next lowest cost, medium primaries - great for those high performance needs, less-restricted flow, not too difficult to install, no tubes pass through the fender wells, have been used with factory V8 Monza mounts with no interference issues.
Cons: Possible road clearance issues, collectors kick out at an angle towards the doors (this is actually good for strip cars).
Notes: Best suited for performance engines.

Hedman Hedders 68330 & 68340
Specifications: 1-5/8" Primaries with 3" Collectors
Pros: Medium-cost, medium primaries - great for those high performance needs, less-restricted flow, not too difficult to install.
Cons: Engine must use front engine mount plate, tubes #7 & #8 pass through fender well (may inhibit turning radius), possible road clearance issues.
Notes: Best suited for high-performance engines, very similar to the Hooker 2129 headers except the primaries are smaller.

Hooker 2129
Specifications: 1-3/4" Primaries with 3" Collectors
Pros: Bigger primaries - great for those high horsepower needs, less-restricted flow.
Cons: High-cost, engine must use front engine mount plate, crossmember requires modification to clear passenger side header, tubes #7 & #8 pass through fender well (may inhibit turning radius), possible road clearance issues.
Notes: Best suited for high-performance engines.

Stahl 123
Specifications: 1-7/8" Primaries with 3" Collectors
Pros: Huge primaries - great for those high horsepower needs, unrestricted flow, no tubes pass through the fender wells.
Cons: Very high-cost, car likely requires modification for clearance, steering shaft must be rerouted.
Notes: Best suited for pro-street or race-only car if you don't mind the high-cost.

Big-Block Chevy V-8 Headers
Hooker 2240
Specifications: 2-1/8" Primaries with 3-1/2" Collectors
Pros: Huge primaries - great for those high horsepower needs, less-restricted flow.
Cons: High-cost, engine must use front engine mount plate, steering shaft must be rerouted, tubes #6 & #8 pass through fender well (may inhibit turning radius), possible road clearance issues.
Notes: Best suited for pro-street or race-only car.

Stahl 224
Specifications: 2-?" Primaries with 3-?" Collectors
Pros: Huge primaries - great for those high horsepower needs, unrestricted flow, no tubes pass through the fender wells.
Cons: Very high-cost, car likely requires high degree of modification for clearance and front engine mount plate, steering shaft must be rerouted, possible road clearance issues.
Notes: Best suited for pro-street or race-only car if you don't mind the high-cost.

Good info for sure, do these headers give any more access to the spark plugs than the original "logs"?

I know I can do the plugs on a Sanderson header setup within an hour. I don't think the 2129's are really any harder to get at as I've only done them once, but they don't stick out in my head as being a royal pain. But then again, after the plugs in my 98 Trans Am, there aren't many cars that are harder to do!

From my experience, you couldn't really "see" the spark plugs on the driver's side with the factory exhaust manifolds. With all the headers I've used, all spark plug changes were easier with the headers and a royal pain with the factory manifolds.

I would like to add that on a SBC using "angle-plug" heads the #3 spark plug will aim right at the uniwiggle of the steering column requiring you to unbolt and jack up the driver's side of the engine just to remove it. I'm even using shorty "header" plugs.

hi Bob, which head design would you consider to be the most easily serviced using the sanderson headers? I was considering going for angle plug heads until now. Thanks.

I have limited experience with heads in that I've only used GM castingss (882, 186, 462, etc) and Canfield aluminum heads. I like the angle plug heads even with the #3 issue as mentioned above, and prefer aluminum heads as they handle higher compression than cast iron heads before detonation sets in and they are repairable whereas cast iron heads cost more to repair than the heads are usually worth. As for which manufacturer I would recommend, I would say it depends on how deep your pockets are and what your goals are. I would ask others what they have used and what kind of customer service they received if they needed the manufacturer's assistance.

I also have a set of ProComp aluminum Big Block heads (they came with an engine I bought) and I'm not very impressed.

DH says check again on 1-November, if they have them I'll post it here so folks can start ordering. I have one paid pre-order so far.
