Big Block Headers, My 3 Cents 
Doug's D320-R
OK, not looking to step on any ones toes, this is what I found works for my Car.
I have been Blogging, Searching the Forums for a while, Yahoo, Googling and asking just about anyone that has dealt with any info for a Set of Big Block Headers that Fit. Had lots of help from others on what worked for them, all good info. I know this is “Long Keyed” but for the amount of Research and time, it’s worth the Read !

Hi All
Getting some parts together for my car, 1969 SSRS and I'm installing a 454, Was a 350/300. Just a street car, maybe a run at the Drag strip here and there.
Read allot about different BBC Fitment issues on the blogs, sometimes you only see the problems.
Was raised and brought up on Hooker Super Comps, ran'em on my cars back in the 80's, the usual ding here and there to get them to fit, can’t believe in this day of CNC and Computer controlled manufacturing, we are still pounding Headers for clearance.
I do not have the Lemon $$ and what I have seen for the 1 ¾” primary tube set, the Headman Elite # 67198 seem to be the easier fit, any ideas for other Headers. I did purchase the BB Engine Frame Mounts.
Going Old School, 15” rubber, nice stance, working on it with my 15 year old Son.
Thanks

I am almost done with a 427 BB (454 Block) and bought a Performance Transmission’s 700R Trans thru Ground Up at their Vendor Show a few months back.
I purchased the Correct 1969 BB Frame Brackets from Rick’s Camaro’s, came in a Classic Headquarters box, 1 ¾” to Centerline of Bolt hole on the Left, 1 3/8” to Centerline of Bolt hole on the Right. Energy Suspension Long BB Motor Mounts 2 3/8” wide. Engine is offset 1" to the Right now.
I have a soft spot for the Hooker Headers and tried to go with them, I do not like the Collector Reducer Bolt at the 6 O’clock position.
I have Power Steering and was told the Hooker 2457's Fit like a Glove, I ordered a set and the # 5 Tube hit right on the P/S Box and the Bolt Hole for the L/H Mount was out like 7/8".
Put a set of Doug’s on a Pontiac 400 cu in for a Firebird a few weeks ago at the Engine Shop I help out at and liked them, looked into purchasing them, called Summit Tech Rep and talked to him, he said the Doug’s were a great Header and should fit, Here we go again.
From what I have seen, the Hooker 2205’s would have worked but that Bottom Collector Bolt bothered me and the Doug’s was not at the Bottom.
I ordered a set of Doug's D320-R, like the Hooker 2205's where the # 5 goes over # 7 but the Doug's are a bit nicer/ heaver Constructed and the Collector Bolt Flange has the single bolt of 3 at the Top, 12 O’clock position.
Another thing for those who ordered their Hookers Ceramic Coated, if you have used the ARP Head bolts, I had marked the 2457’s in 2 places each side where I would have had to Notch the Header attach flange – Doug’s have Plenty of room.
I also have a Hamburger “Kick Out” pan, old style where it does not have the Cut out to Drop the Oil Filter, the Doug’s has an Opening between the Primary’s where I can reach in from underneath the Frame and remove the Oil Filter, Hooker 2457’s did not have this.
I do have to Re-route the New Stainless Steel 3/8” fuel line up front, Cut about ¼” off the Right Upper AFT “A” Frame Pivot Support Bolt and the Pitman Arm from the Power Steering Box has about 1/16” clearance to the # 1 Primary Tube, and I do not have any Suspension on the Car Right now, so I do not expect any interference with the Idler Arm as I have looked and there seems to be plenty of room on the Right Side.
I also made a Beautiful 700R4 Crossmember from the TH400 BB one and relocated the Mount to the Front. Cost me $75.00 and some MIG Time.
I will post some Pictures, Bought the Doug’s Bare Metal and will be sending to Jet Hot for their Ceramic Coating service. I have measured and looked at every angle on this install, Doug’s worked for me.
