Zach said he has a 312 not a 239

P.S. Zack, best talk to them; they used to be in Northern Ca. 

My guess is they will not work on a 239 1954 engine because the exhaust ports are very small compared to the later years, thus they will not seal properly.

I CHECKED OUT THE ONES FROM RED'S AND THEY ARE ABOUT THE PRICE RANGE I AM LOOKING FOR. I WOULD LIKE TO RUN LARGER THAN THE 1-3/4 INCH. I WAS LIKING THE DUEL TUBE OR THE 2 INCH TUBE ONES. IT LISTS THE EARLIEST YEAR AS 55...HAS ANYONE GOTTEN THEM TO RUN ON A 54? THEY SAID THEY WON'T WORK, BUT IF ANYONE HAS DONE A MODIFICATION TO FIT, THAT WOULD BE AWESOME.

THANKS AGAIN,
ZACH

Since you've got some time, try taking a look at this.

You will need a floor shift for the Rex headers.

This company makes headers for your car:http://www.rexhp.com/fuelblocks.html.

THANK YOU EVERYONE FOR THE PLACES TO CHECK. I REALLY DO APPRECIATE IT!! 

Doesn't the 57 and later manifolds flow almost or as good as headers? If that's the case then you will have 0 fitment issues.

I have a set of 57 Ford car duel exhaust manifolds if your interested, $200 including shipping. ,  the stainless for $200  looks like a good deal.
