Default Best 2nd-gen F-body D-port headers?

I have a friend with a '77 T/A, 6X heads, and some nasty old 3-tube headers.

I have him interested in installing some good 4-tubes. My dilemma is that I haven't bought a set of headers for a 2nd gen F-body since the 1990's!

What are the best options? Something about 1.75" primary is plenty for him. Doug's? Are Tribal Tubes available??

Thanks,
Lee

you forgot to mention what power level it is for?
Hedman 28150 is a good install as well if 4spd car.

Automatic, mild 455/6x/mild HR, pure street. This guy has owned the car since '78 and it has NEVER been to the track.

I'd just go with the RARE RM-2-OS factory headers. It's an easy fit and they work really well. If not Doug's seem to be a good way to go I know a lot of guys use them.
Good luck

when measuring the overall 'drop' the tribal tubes were 3.5" inches shorter than my hookers IIRC I cant say how much additional ground clearance i'll gain as I don't have the tribal tubes installed yet

the doug's headers are VERY nice
i put the on when i had the ED-heads on
fit was perfect
just get some ARP 5/16 header bolts, or studs
makes the install so much easier

Lee, I have recommended and use the Hedman #28150, 1.75" x 3".
Use the composite header gaasket from Fel-pro 1423 (or maybe 1424) either one is for a D-port.
They have good ground clearance and fit well, even on a lowered car like mine.
Looking underneath and across the bottom of the chassis, the lower tubes hang just below the frame rails.

Thanks for suggestions guys!

Good to hear that Hedman is now making a good product for these cars. I looked at a set back in the early 90's, and the flange openings weren't even shaped liked the Pontiac ports! But I recently bought some Hedmans for an LS-swap project, and they are gorgeous headers!

I've got an offer on an old set of Hookers - never used. Those will be a serious consideration.

Larry, thanks for sending Steve H. my way, he's a very nice guy and I enjoyed working with him. He has the 2.5" RARE's on his '79 400/4spd. S/E. Even though he only has about 8.3CR, we were able to get 314rwhp out of it! With the low CR and RARE's, I wasn't expecting it to go higher than maybe 280.

I'll discuss the options/costs with the owner, thanks again.

X 2 on all of the above.

I even put a set on the wife's 79 T/A way back from stock manifolds/pipes to headers without raising the engine. Installed from underneath. Just dropped the starter and oil filter housing and they bolted right up.

NEVER MIND....

For the moment, the guy has decided that he is happy with how his car runs with the 3-tubes.

"you can lead them to the water, but...."

Thanks for the offers and the info, maybe this thread will help someone else in the near future.
