Thought I found some sweet headers... Did I find something better???
I found these hooker super comp long tubes on an 89 fox body at the local pick a part. I thought wow, what an awesome find!
Well, 1.5 hours in to taking these things off I notice a 351W stamped on the top of the block. I promptly googled whether 302 and 351 headers were interchangeable. After a limited amount of research i determined they're interchangeable but there may be some clearance issues. I'm sold and spend ANOTHER 1.5 hours removing and buying these things for $35 a piece.
When i got home I looked at the bbk shorties that came with my 88 5.0 and noticed how terribly different the bolt pattern is from my new junkyard headers' bolt pattern. What gives?? I thought the 351 and the 302 had the same heads/exhaust ports???
1. Did that 351W have some kind of crazy awesome aftermarket heads with giant exhaust ports that required such ridiculously large long tubes?
2. Should/can I go back to the junkyard first thing in the morning and grab those heads to slap on my 302 w/ e303 cam and cobra upper lower?
3. Are these headers worth anything with the dents and ****? How much could i resell them for and what would i say they are?? haha
4. I am able to return them within 30 days if that's the better option??

GO BACK AND BUY THE HEADS THESE WERE BOLTED TO........
That bolt pattern is for an aftermarket head like a TFS high port.
BTW, Hooker headers are sort of famous for having final fit problems, thats why I have a nearly new set up in my storage loft..........

I'd see if they are old tfs high ports, like said , they are of a tfs high port pattern and I'd look closer at the heads and see if they might be the old tfs cast iron high ports, if they are, they carry a little value

While they may be the TFS high port iron heads. That pattern did not come on the old TFS heads you had to drill them for it. The old TFS had a stock pattern that was just raised .75 of a inch.That pattern came out on the old Alan Root head that came out when the 5.0 was taking off but that head never came in iron. I have also seen adapter plates so you could add the big tube headers to stock heads. So I guess we will just all have to wait and see.

Should I use these big tube headers or stick to the bbk shorties it came with? (I currently have ported stock heads, e303 cam, cobra upper and lower, 70mm throttle, CAI, bbk shorties,off road H pipe and flowmasters)
Will these beat up hooker headers and a bassani X pipe show a significant improvement over my current shorties and H pipe?

As beat up as those headers are I really wonder if they are worth putting on the car.
You could try and repair them but I think you would find that futile.
They would help in the lower RPM ranges however if you could fix them.......

LOL just showing my age LOL
OP, they can be fixed and stud gun and a slide hammer works wounders But that being said those are not cheap headers. I dont think you will like the ground clearance with them on a 302. if they even work. I also think they are way to big for your comb. maybe sell them or hold on to them for a big CID 351 engine.
