You need to read the footnotes towards the back of the paper catalog (I kept some mid seventies, that is to say just Hooker and Headman catalogs), as they will tell you the exclusions. On line the adds hype the big print giveth by saying: "It will fit!", but the small print; which is the foot notes in the back of the catalog, "taketh away" (NO it won't fit if you have any of these accessories or heads/car combinations!)

I gave up on the over the counter header companies as they have one model that fits every Chevy Car body made with-in the same series (example '67-'69 Camaro, which excludes 1970-'81, 1982-'92, 1993-'02, 2010-'15, and 2016 and up). That one statement excludes a lot of cars.

Second issue is no one you see in car mags makes even a SBC header for a full size. That header is designed to fit a Camaro, Nova, Chevelle, Monte Carlo and the full size. It is a universal header You compare he part number with the cars they claim it will fit), but that means it universally doesn't fit any of these car bodies with out beating the tubes.

I gave up on buying an off the shelf header and instead buy a header kit.

There are a couple of comapnies that offer header kits in stainless so it will last the life of the car body. I used this company to build a set of stainless steel headers that fit my car and engine combination:

Now I can weld structural steel, but I could never be a surgeon (which disappointed my father who started med school at Eaton, but WWII got in the way). For thin metal that has to be welded with inert gas inside and out I went to a muffler shop that does this every day. It cost me $1,300 to get a custom made header and dual exhaust out to the back bumper. Compare this with a Lemons header that is also custom made to fit your car, but doesn't include tail pipes or mufflers. If he doesn't have a previous build of your car body and motor (he probably does as it is a fairly common build), be prepared to ship your car to California and back to get him to build a set of tubes for you.

Or you can go to any muffler shop and talk to the owner/manager to build your custom made headers for you.

No off the shelf header will fit. As off the shelf headers are designed to fit a motor installed in the stock location (only an issue with a first gen Camaro, or 1968-'74 Nova), that have heads with sock port locations and shape (square not round).

All of the off the shelf header companies were started by men who owned a muffler shop and saw the need for tubular headers to fit the needs of hot rodders.

Jere Stahl learned header design by reading an engineering text book on exhaust theory, but he still owned a muffler shop, and wanted to improve on other four tube headers offered by his competitors.

Doug Thorley first invented the Tri-Y header in 1958; based upon an idea he had in matching cylinders to extract more gas. He owned a muffler shop and made headers for local racers were he earned a reputation as an innovator.

Bob Hedman Hedders, began as a one man shop in 1954. He sold his headers on the dry lakes to racers looking to make maximum horsepower. He owned a muffler shop he ran during the week and raced on weekends looking to go as fast as he could.

Gary Ronald Hooker's secret was to make his home made headers longer (produces more torque) and the tubing larger (produces more horsepower) than what was already available. He didn't own a muffler shop but was a drag racer and an athlete (runner). He was also one of the few who had a college degree studying design and electronics. His partner Elwin Westbrook was a welder who had the fabricating experience who made cages for race cars on the side in a rented shop he shared in 1964 with Hooker. Together they sold Hooker brand headers; more than any one else selling headers, as they weren't welding up exhaust systems during the week in a muffler shop, but only made headers.

All of these header makers sold their business and their names to large corporations who make most of their headers in Mexico (still labeled made in USA under NAFTA), but the Mexicans merely feed welding robots tubes an automatic tube bender bends to a fixed program. Then they place the welded product in a box and ship it.

Yes they have .375 raise ports
Try Sanderson block huggers. I got them to clear the steering box on my '68. I have a 496 with raised exhaust port heads as well. The driver side will have to go in from the bottom. Remove the oil filter to help with clearance.

I have a set on my 66 Impala SS I would sell!

I have a set on my 66 Impala SS 396 Auto with P.S.. I have never cared for headers as the're hot, and continually loosen and I'm not a performance car guy - just a cruiser. Also I'm not 100% sure they would fit your application. The car came with them and I have purchased exhaust manifolds to replace them.

Stock manifolds will strangle a 496.
