Flowtech Headers
 

ANYONE EVER INSTALL FLOWTECH HEADERS ON A 289 HOW DO THEY FIT

Dude!... I'll let you know tommarrow! I just got mine UPS today.
I'm putting them on a 65' 289. I bought the 12102 Flowtech I std finish. I'll send you the instructions if you tell me your e-mail. I don't know if I can get it big enough to read. :D

ok... here's the scoop. I had to lift the engine up about 2-3 inches to get the headers in. They didn't get in the way of anything, but I don't have air or power stearing. The driver side header slightly covers spark plug hole in the head so it had to be filed down. I cant tell you how they match up to stock exhost because I put on aftermarket duel(Which bolted up like crap, don't buy the duel exhost kit from mustang's unlimited). That about covers it...

mmmmflow tech
 

i got those i had to remove the clutch equalizer and z bar but they fit or slide right in and sound ok
they bolt up fine and i added dumped pack nasties to mine :D :D :D

You didn't have promblems with the spark plugs?

uhh y would u
 

have probs w/ the plugs?
what kind of probs?

The spark plug hole was slightly covered by the headers,(the part with the bolt holes)

I bought a set of Flowtech shorties a few years ago and thought they would fit in my '82 GT with a 351. Come to find out, they fit the engine but not the car. Since I already hammered on them, I couldn't take them back and ended up buying BBK shorties made for a 351 mustang.
Anyway, my point is, I think Flowtech headers are made of pretty thin metal and are not high quality compared to other headers on the market.
I'll sell them cheap if anyone wants them.

uhh
 

still dobt know whatcha mean with the holes?
sorry
