I didn't, and was happy to have an option that met my budget. I also like the stock look. Mine are OTB with Comp 10* locks & retainers, and Engle double springs. 4 years now with no issues. Someday, I may upgrade to something like EZ's, but for now I'm happy, and wouldn't hesitate to reccomend them to anyone looking for a budget street / performance head.

I remember when I bought my EZ heads from Dwayne Porter they actually came out to be around $1700 to $1800 which I figured was about $300 more then the Eddy's. I also bought the smallest EZ's with the stock exh port location and I dont need offset rockers. And right now these flow about the same as a nicely ported RPM head. But my EZ heads can still be worked more for more power as its full potential is more then the Eddy RPM's I believe and thats why I spent the extra money. I hope one day to step it up a tad more and have the heads really worked then. I dont blame anyone who is just building a street car on a budget to go with Eddy's or Steakth's. But I am very happy with my EZ's since everything is of stock type and I need no special parts. It even oils like the standard head and I dont need the rear oil tubes to the heads.

I know he is looking at what he can afford to do right now, and based on that the stealth's look to be the way to go. I would hate to see him do this if it's going to kill the power potential of the engine. Anyone here have his combo in an engine that has had it on a dyno???. What kind of hp and torque numbers will this make. I know he was hoping to be in the mid to upper 500 hp range. Thanks

If he has heads that flow between 260- 290 cfm now then he should be looking to step up unless his goal is to fool the non mopar person into thinking he has stock heads .

Especially considering you will have $1400 into the Stealths by the time you upgrade the hardware and have a valvejob done and $1900 into RPMs by the time you have them checked out and a valvejob done. My question now is, what is the low lift (.400-.600 lift) flow like on the EZs compared to the Stealths and RPMs for those of us running smaller cams in the mid .500 lift range? Also are there any costs on the EZs I'm forgetting like the need for different pushrods or valley tray? Thanks!

They are probably the best bang for the buck, they just happen to be the most bucks. Usually when people say they want bang for the buck they're more concerned with the bucks than the bang. That said I've got Stealths on my engine and they looked pretty nice OOTB, CCed all around 80 cc. I needed dual springs so I changed those out. They come with Comp hardware now. Now I need to pin those needles, got to feel that heat Hear my motor screamin while I'm tearin up the street

Thanks My combo is 8.97:1 493 with MP509 cam, RPM heads and Holley TBI on a single plane M1. 500 hp@ 5000 and 600 ft/lbs@ 4000. Does it on 87 regular. It carries at least 500 ft/lbs from 2000-5000 but it drops pretty quick from there. The heads are basically OOTB with the valve job fixed. Kevin

I only ask because my EZ heads at .600 were 329 on the intake and 223 on the exh. The last ported RPM head I saw was like 225 at .600. Its just 262 at .600 lift seems like alot on the exh of your head. Dont mean it to be smart just want to be sure thats correct. Ron Last edited by 383man; 01/30/14 03:23 AM.

The Indy EZ exhaust? 290 cfm @ .600" & 308 cfm @ .700". Been there, done that.

Some guys use a tube on the exhaust to inflate their exhaust flow numbers by 20-30 or even more CFM. To quote one of the better head guys out today (Darrin Morgan). Exhaust port airspeed is more important that exhaust port cfm. Aim for 300+ FPS and the exhaust WILL get out. You will hear a bad exhaust port on a flowbench just like you will hear a bad intake port. Its all about port shape. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

I agree but I just have not seen exh numbers like that on the basic EZ , Stealth or RPM heads. Ron Last edited by 383man; 01/30/14 06:16 PM.

I apologize for being inflationary and not up to snuff as to how the big boys do it. In my defense, every engine we run on our dyno and every engine in every one of our cars has some kind of tube connected to every exhaust port. Do any of you run straight out of the heads on your cars with no other exhaust system? I'd like to say more, but inflammatory along with inflationary would be infra dignitatem.
