Since '71-'73s didn't come with Windsors, could that be the issue?  I know they came with 302s, but I'm pretty sure there's not a 'one-size-fits-all' solution for 302s ranging from '64-'73.
Well, the 302 is a Windsor!

OK - but that begs the question: is a 351W basically a bored & stoked 302, or something different (as in, the block is somewhat different to accommodate the greater displacement)?  I honestly don't know - never been worried about anything but the 351C that mine came with, so I'm not exactly up-to-snuff on other engine trivia.  

The heads are what dictates the header fitment - someone with a set of Cleveland heads should be using a set of Cleveland headers, then chase the other issues that come with the engine mount height and block dimensions - i.e., Clevelor engines (which I'm sure is not the case here).  

Aside from that, gotta determine if the block dimensions differ significantly enough to create the header fitment issues he's running into.  I think Don C's response above speaks to that.

Yes a definately height difference in the blocks weteeen the 302 and 352 Windsor's. When I was sent photos of the engine by the seller he wasn't sure what it was but from googling how to tell the difference apart from comparing measurements of a 302 & 352 side by side, the quickest way was if you could get to the lower bolt on the thermostat housing with a socket it's a 351 if you can only get to it with a ring spanner it's a 302. 
You right in one aspect that the 351c came out in the 71-73s that I know if however the advertising on the hookers specifically said they would fit the 289 up to the 351w for stangs up to 73. In fact the wrecked donor Grandé here in NZ I got parts from had a 351w in it as I scored the correct power steering bracket. 
At the end of the day I'm just going to have to make the ones I bought fit either by cutting the flanges off or cutting and having them modified to bend down more

Sounds like you've got a solid handle on it.  Good luck!  thumb

Cheers mate. Will take too long to source replacement bring half way around the world from the best source of parts at reasonable prices.. lol. We have to rely on kiwi ingenuity to make things work! (Not mine though!) Ha ha

Actually the quickest way to tell whether it's is a 260/289/302 style block or a 351 is to look at the distance from the top of the water pump ports in relation to the top of the block. this can easily be seen in a photo of the front of the engine so no need to actually be with the engine to put a wrench on it.

The 302s (and 221s, 260s, and 289s) up to 1973 had a deck height of 8.206 inches, and the 351 Windors, up to 1973, had a 9.480 inch deck height. In 1973 the deck height on both the 302 and 351W deck heights were increased by 0.023 inches. The 351 Cleveland deck height is 9.206 inches.

This means that the 351W block is about 0.9" taller and 1.8" wider than the 302 and about 0.2" taller and 0.4" wider than a 351C.

Thanks Don. 
My engine is actually a 1974 too I just realised and might even be slightly taller. I actually think their jig when they make the headers is out as all the forums say they tend to only hit on the driver's side .There was 1/2 inch clearance on the passenger side. The flange / collector also looks like it is angled inwards from the other side
