I was looking at ordering a pair of these but I do not know if it would be worth it. Will I get a lot more performance out of these heads over stock on my Indy?

yes you will, plus they are more durable than the stockers... I'd go with these heads http://www.hughesengines.com/partDet...amp;eTypeID=10 slap in the 2.02 valves and have hughes do their magic to them and they will out perform the r/t's...

 

What kind of numbers can I expect from these? I basically want my money to be well spent and get the most noticable gains out of what I buy.

 

they specify the flow rates towards the bottom of the page. as far as HP/TQ #'s go, it would depend on the other mods that you have and how your building your motor. my 2000 5.9 was a 4x4 QC so I was loooking for the best of both worlds, low end torque & decent upper end HP. here is how I built my motor...

52mm fastman
r/t heads (the heads I mentioned above were not avaiable back then otherwise I'd have put them on)
gibson headers
dual out 2.25" flowmaster cat back exhaust
FIPK K&N kit with a 6x9 round filter
MSD 8.5's
MSD off-road coil
MSD off road spark box (equiv to a 6a)
autolite 3923's
crower 1.7 roller rockers

if your after HP, then make your motor flow as much as it can at WOT, if you want torque, open it up too much and you'll loose part throttle torque (costs you mpg for everyday driving).

 

So far my modifications to my Indy are, Long Tube headers, (no exhaust for now but will have 2.5 inch dual exhaust soon), Ported and Polished my own throttle body (had a machinist make me some new butterflies), some NGK Platinum plugs, 180* T-Stat.

I think my truck should be able to run 15's I have never brought it to the track but I was at the track and a normal Sport 2wd 5.9 Ram ran 14.92 with those mods plus a chip.

 

ah, ok much clearer now... yank off your intake and cut the runners down 1.5", this will move your power up off idle and allow your motor to breath alot better in the upper rpm range. this will definately help your 1/4 times out. it will not hurt your low end too much if at all. I did this to my motor as well and really liked it. experimenting, on the next manifold I only cut .25" off the runners and did not notice much of a difference... 1.5" is the way to go.

 

What exactly do I cut off? And what tool should I use?

 

take off the intake and remove the plenum off the bottom of the intake, you'll see the runners there. take a ruler and at the tallest point, measure down 1.5" (for a 5.9 motor) and mark it, then draw a line over to the edge of the intake wall... I have a picture on the other computer I can post later... cant access it from this one. I used a roto zip and a dremel cutt off wheel. cuts it like butter but you have to have a soft touch with it, they break easy. my last intake took me about 3~4 hours to cut, cleanup & button up before re-installing back on to the motor. well worth it.

 

I didnt know if that really worked or not. Do you have any performance results from it? ie: times, dyno charts, what have you; to see exactly how much it does help. I mean, if it works, it works, and for a free mod ( minus gasket costs) thats pritty cool.

I too am contemplating r/t heads as a cost effective mod. I think edelbrock heads would be the way to go, but I want to run some more mods and Im running out of disposable income, because school started up again and I dont currently have a job...soooo I may just run some r/ts for a couple extra ponies, and cut the intake, plop a pcm in there and hope for 14.5s.

 

nope, no data to back it up... just the butt dyno in the mountains. pulled much better on the steeper grades than before the mod. the motor breathed really wellup to about 5k rpms. my truck was a wheeler not a 1/4 mile truck... do some more research on the weband you'll see what others have to say about the mod.

Heads are not a cost effective mod, if you want to save the $ go with the HD heads... with the mild porting & 2.02's will out flow both the eddy's & r/t's.
