Headers

[gnr]

Suggestions on what headers to use on my 72 duster. Has a 318 and I am changing heads to 360 heads. What's the best header as far as easy install or should I get a descent set of each manifolds. Manifold in it now are 318 two barrel so ports are tiny compared to 360 four barrel

You will lose a LOT of compression putting 360 heads on a 318, FWIW.

yep!

As far as headers a lot of guys have used and liked Doug's headers. The cheap ones put 3 tubes under the tie rod linkage prone to getting banged up.

I just installed Doug's D453 on my 318....not too bad at all.
I'd go with Doug's again.

IF you do exhaust manifolds, driver side 340 & early truck Magnum passenger side. (2-1/4)

Dougs is an excellent choice header wise.

Wow I guess I better do some research before using 360 heads. Thans

Did you gain any power going with headers on your 318 ?

Don't know yet.....but I can say without a doubt they'll flow better than the stock manifolds.
