Honestly, the headers will help in the long run with the ported intake
and heads as well as in the interim. Definitely ceramic-coated for
longevity and cooler operation (header temp).
As for the times, a good friend had a 1998 5.2L 4x4 and was running mid
14's with it (Powerdyne, TB, headers, cat-back, MSD, and 4.10 gears on
both front and rear diff's).
If you're going to be doing a lot of offroading, keep the factory
manifold stock as well as the heads. No need to port them since that
will raise your powerband into the higher RPM range. This is great for
racing but bad for offroading where the average RPM is 1500-2000max.
(Not 3000-5000rpm)

Subject: DML: Which mod to do next!
Hey folks,
I've got a couple of questions for everyone. I'm debating the JBA Header
buy and want your unbiased opinions:-). Here's my current setup:
98 5.2L 4x4 Auto
Leach PCM (Setup for the Supercharger)
180 T-Stat
3923's (About to be 3922's)
MSD 8.5 Wires (No sh*t, these actually made a difference)
50mm Flow Metrics TB (Ground the Air hat to fit TIGHT)
Gibson Catback Dual Exit Behind the Tires
K&N Cold Air Intake (Until the SC shows up)
Gatorback Belt
Black Magic Fan
24# Ford Injector's (Not installed until I get the SC in and tuned) IAT
box PowerDyne SC, with Randy's Tensioner, both the stock 6PSI pulley and
also the 9PSI 7RIB pulley (Everything BUT the Supercharger is here, it
should have been here LAST Monday, Powerdyne must be having a bad week)
Now here are the questions. What makes the most since for my next step?
The headers, a new ported and better flowing intake manifold, free flow
Cat, new CAM, or MSD6BTM / Coil / bla, bla? Or anything else you can
think of. A few questions come to mind about the headers, such as being
a 4x4 I will have this sucker off road, do I need to worry about the
headers getting wet, how much maintenance are they (how often do I have
to torque them down), and since I don't have a fan clutch anymore will
the Headers throw off more heat and make me run more of a risk of
overheating??? I am really concerned about the additional heat, am I
wrong to think this. What about the headers getting warped from going
through a stream and what not? Will the Silver Ceramic Coating keep them
looking fresh? And really what kind of difference will I get out of the
headers vs another mod. If I get the headers then that's it for a month
or so at leastJ. Also on the 98 5.2L 4x4 Auto I assume I need the
Ceramic Headers AND the Y-Pipe?
Now, I hear people knocking the 4x4's and their speed. I damn sure would
like this truck to flat whoop some ass after doing these mod's. Truly
what should I expect for 1/4 ET's out of this sucker? I can tell a HUGE
difference with the few mod's I've done, and I know once that Powerdyne
is on it will blow me away (I really am probably going to do a 50 shot
on top of it before long). In the end I'll have a new Intake Manifold,
Cam, and probably Ported & Polished R/T Heads. But these last mods will
be done over some time. I guess I just need some direction and general
advice.
Any advice is appreciated!
Shawn
