I figured I post this here since that is where I would expect to find this combo. Back in the 70's, there were a number of Boss 302 powered Mavericks out there. I personally saw one at Drag City in North Jackson, Ohio. I remember someone was quite successful with one in the old Competition Eliminator class and a couple of magazines ran some pics of them. My question is, who's headers did they run? I contacted Hooker and was told they didn't make them. Hedman doesn't list them either. I've heard Tubular Automotive may make them, but other than that, nothing. My old '70 Boss 302 had headers however, it's been so many years since I had the car, my feable old brain can't recall. John Vermeersch of Total Performance in MI used to have a lot of oddball header combinations, but I don't know if he is still around. With the availability of CHI heads and another "soon to be available" cleveland head (I'm sworn to secrecy), I think one could build a 347 street/strip motor that would really rip in a light Maverick. I know there are great Windsor heads out there, but I have run a number of cleveland headed engines and I love the looks and sound of them.

Tubular has been doing B302 and 351c headers for a very long time. A Pro-stock 351c racer turned me on to Tubular in the late 80s. He campained a 351c Pinto in the 70s. At that time he built his buddy's 351c Maverick, using Tubular headers way back then.
Fwiw, I had a set of the B302s and they are impressive with their monster tubes. If I am not mistaken, they were 2.125" tubes. I bought 351c headers, and they accidentally sent me B302 headers. I had them for a year before I went to use them and found out they were the wrong part. Tubular made it right though and sent me new headers, even after all that time.
Total Performance is still around.I bought a set of Headers from John last year.Haven,t installed them yet.
This is way way after the fact, but ijust noticed this post. Hedman made headers for the351c and 302boss installation. They 2" to a 3.5 collector on the 302, and i think the 351 model was a 2 1/8 to 4" collector. The sets used standard engine mount, and to the best of my knowledge, neither required serious shock tower surgery for installation. Plug changes were likely a serious chore. They were shown as pro stock headers. There was a 302 boss comet in my area and they ran the hedman headers. The headers used the flat collector design that hedman used sometimes. To the best of my memory, the car had untouched shock towers.
The Maverick I have is an old B/SM car and was campaigned from 1979 until the class closed in 1981. It originally had a Boss 302/4spd, 318ci and ran in the low 10's. The headers were built by Bill Dawson in L.A. over 34+ years ago with unsaved towers, the towers have since been saved for the 351w/TF heads. Fast forward to today and it runs a 408w with Powerglide. The headers on it were built in 1991 when the engine trans were put it and also done by Bill Dawson. They are individual tube and are stepped from 1-3/4" to 1-7/8. Chris Hill of SPD did modify the merge collectors to give me a little more torque and the motor responded on the dyno with 642hp at 6800rpm. The car in my avatar is a picture of the car when it had the Boss 302/4spd.
I tell ya what John,I believe you switching over to a cleveland style hd is probably going to get you as much power as any of the windsors.I think if someone tried using an after market 351w blk w/ cleveland mains and the old style 351 4v hds,and put the hardware in it to spin above 7500rpms you could still out run a whole lot of cars at the track.I don`t know if the old BB Chevy 840 hds have any larger intk ports than those old 351 4v hds did.
