:cool: Okay, I have 1 3/4 inch headers, but the Headman Headers I have really tuck up nicely. I'd go with Headman.

Do those heads have raised exhaust ports?

I have Hooker Super comps on mine, 2” primaries 3.5” collectors. On the stock height heads they fit ok, a little tight on the steering shaft but no contact. Didn’t have to dimple any tubes and plug access wasn’t bad, never burned a plug wire with them either. They just hung pretty low

My current heads have a .300 raised port, and while that didn’t sound like much the headers fit terrible. Had to dent the #2 exhaust tube to be able to even get the #4 plug to thread in at all. Had to dent two tubes on the drivers side to clearance the steering shaft, still haven’t got my Z bar back in but it had a lot of clearance before so that shouldn’t be a problem. I can’t recommend these headers anymore, though I have heard that the regular hooker competition headers fit much better than my super comps do.

Seems like even the Summit brand fit your later cars well. Hedman are the "go to" small tubes for earlier cars like mine; I'd have to assume they fit 68-72 as mint.

PS engine pro told me to keep the 2" primaries for 600 hp, fwiw.

When I switched heads I was in the same boat. Needed to find 1 7/8" headers. I found 2 options that checked every box. Patriot and Dougs. I bought the Patriot's because they were $200 cheaper. I should've bought the Dougs. The Patriots hit at the lower control arm frame perch on passenger side and the frame stand bolt on the driver side. I know a guy with the Doug's and he said his fit without having to hammer on them at all.

I have Patriot 1 7/8ths coated with 3" collectors on my 489 with race rites and fit is great, needed 1 small dimple on drv side motor mount frame stand rear bolt head, I made big lol, engine/dyno shop owner said there's more power with 2" but I can get to the plugs fairly easy, probably wouldn't have been all that bad with 2" but my back's a pita
