B Block in an A body...only 2 ways to go, underchassis or fenderwell...pluses and minuses to both depending on street driven or not. Some people drive fenderwells on the street but the exhaust system can be unsightly but the maintenance on engine/trans components is far easier than underchassis. Underchassis are somewhat "cleaner" from a traditional engine compartment standpoint and exhaust system is easier but install and maintenance on engine and trans is a NIGHTMARE...IMHO...TTI's underchassis are what we have on our BB Duster...nice headers...but wholly jeez!!! And don't even ask about starter R&R... panic

I love my Hooker fenderwells. They aren’t in the way when doing maintenance. I have 205/65/15 front tires. Have never tried to put anything else on there so I can’t say if they’ll fit with your tires.

I have the big 2 inch to 2 1/8 TTI headers on my Duster. It has taken some time to figure it all out but I think I have a system now that allows me to take the car apart and put it back together. I had to build some tools and fixtures to make it all happen. Basically the front suspension has to come off and then the headers come out the bottom. Or you can drop the entire engine and trans out the bottom with the headers attached.

I used Proparts semi-fenderwell on my 9 second Dart. IIRC 2 tubes go through the fenderwell on the drivers side and one tube on the passenger side.

Yes we went with them on our A body Aussie Valiant, tire do touch on lock but that is the only problem. So easy.

iagreeThe only issue I have is the tight fit with the no logo Indy cast valve covers, had to notch the outer edge for two tubes on the passenger side.

No, his have bigger primary tubes, Pro Parts where two inch, Maz are 2 1/8 shruggy
I bought a set of the original Pro Parts from Bill Bgashaw before he sold out and close the doors on Pro Parts for my 1969 GTS Dart 383 4 speed car, they don't fit worth a hoot on low decks with stock heads down
I called him about this and was told their for 440 motors in A bodies with stock heads, not low deck B motors whiney shruggy

Funny this came up right now...I'm in the designing stage of building a 67 Dart and I'm hung as whether to go stroker small block or big block...one of the deciding factors is headers... work

How fast you want to go would be my biggest concern. If you are happy in the 10's and slower a small block stroker in a 67 Dart is the smart choice. Lean on it a little harder and you are in the 9's.
