This one's been idle for awhile but I'm bringing it back up. I'm having the same problem. However, I have yet to get a chance to check all of the afore mentioned common leak areas. I'll get to that soon but wanted to bring up another possibility... a buddy of mine told me he's seen the same...

What's your goals for the car? And keep in mind that they might change a couple years down the road. Maybe consider a platform that you can easily modify in the future if you're looking for more power. How are your mechanic/fabrication skills? You might need to make a few custom brackets and...

Thanks for the pics and good info. I currently have the 440source adjustable rockers and figured I'll be able to retain them (MP heads use stock rockers). Is there any reason these rockers w/ be subpar for the mods I'm making? What lifters would you recommend (that fit the stock lifter...

Thanks for the reply 68. I ordered the Cloyes hex-a-just before reading your reply. I also got their cam button. I'll see how it fits and dimple the cover if I have to. That's a sweet ride you have there.

I'm not sure how far in the hole the pistons are. That's the 1st thing I'll check when I pull the heads. You're right about the 311 heads. I'm going to go w/ the 524 now. I'll send them to Modern. I've already purchased a Cloyes hex-adjust double roller timing set w/ a thrust bearing...

Can someone educate me on what I need to do for cam thrust when switching from a flat tappet to a hyd roller cam? My understanding is that the lobes on the flat cam are tapered to make the lifters rotate. This forces the cam to the rear of the motor against the plate. However, a roller cam...

Gear is a 4.10 w/ 27" tires. I have a 3.55 I can swap in for street driving if the 4.10 gets annoying (and it does above 55 mph). Car weighs 3400. I'd like to get into the mid to high 11's. 550hp would be awesome but I'd be happy w/ anything over 500. I can spin the tires at 20 mph or so...

You guys make some good points about keeping the iron heads and possibly adding nitrous. I agree that I can reach the same goals and save money going that route. I've made up my mind on going w/ AL heads though... I like the increased flow, lighter weight, hopefully better sealing valve...

Alright, here's what I'm going w/: MP 5153524 heads CNC ported Edelbrock Performer RPM intake (they don't make an air gap for a big block do they?) 750 cfm carb (I'll take any advice here) Hyd roller cam (probably XR274HR... 224/230 duration at .050", .574/.570 lift w/ 1.6 rockers)...

Thanks for the #'s womanator. That's the kind of gain I'd like to make. I'm not familiar w/ the specs on stage IV heads. How do they compare to the "452" and "906" MP heads?

I'm not an engine guy so correct me if I'm wrong, but my understanding of quench distance is the distance from the piston to the head. In other words, and amount that the piston is in the hole plus the thickness of the gasket. In your case that would be .120" for a shim gasket or .140" for a...

Now I'm not so sure... I'm finding a lot of posts like this: http://www.cuda-challenger.com/cc/index.php?topic=52902.0 I know that's just a few folks opinions but the exposed gasket and dropping valve issues seem to be repeated on several forums. So, back to the MP heads. Everyone...

Good point. The #'s and price of the ported Steaths are hard to pass up. And after all, I'm not building an all out race motor... just a strong street motor. How bout the induction? Am I giving up more then 10 HP there?

If I can find a CNC ported version of the MP heads I'll probably go for them. The off-brand, China made stigma of the Steath heads has me a little worried. However, I haven't found a ported version of the Mopar head yet. Does anyone know where I can find one? Also, what intake/carb combo...

How does 290 unported, 315-330 ported sound? http://forums.moparmusclemagazine.com/70/831135/mopar-racing/alumn-stage-6-heads/index.html
