Replacing Camel Hump heads IE180 or IK180??

I am looking to replace my 462 camel hump, 64cc, 2.02" heads due to a crack that has developed. I am basically on a no-string budget, so I am looking at the "cheaper" assembled head options: Brodix IK 180 & Dart IE 180. Both heads are 64cc.

Other than one being iron and the other aluminum, what is the difference that I am missing? I ask because I find it odd that the Brodix is 200-300 dollars cheaper than the Dart IE even though it aluminium. I would have thought that the cast iron head would have be cheaper......

Is the Dart IE a step-up performance-wise over the Brodix even though it is cast iron? Or are they on par with each other?

The heads are going on a 327 with: 11:1 compression, Isky 280 Mega cam (.485 lift, .050 is 232 degrees on I&E), Comp Cam Magnum roller tip rockers, Carter 750 AFB, late 80's GM LT1 aluminium hi-rise intake. The car is a 4 speed, 3.55 rear.

I also will admit I'm not 100% understanding the flow numbers when I look at them. Is more always best? And with a .485 lift cam, should I be looking at the .5 lift only, with regards to flow numbers?

thanks.....

Trick flow makes a aluminum version of the double hump if you like what you have. I do think they flow a little better than the iron ones though.

The TF 175 head has a 60cc combustion chamber 2.02/1.60 valves

Given how hard it is to find a original camel hump that is not cracked or has been decked 2-3 times already these would be my choice

Have you looked at Edelbrock heads ? I replaced my camel humps with their E-Street heads and they really woke up my 327. I have an ultradyne 270 hydraulic cam so should be similar to yours. About $1000 for the pair.

Re: Replacing Camel Hump heads IE180 or IK180??

When my son was rebuilding the 350 in his truck, his heads turned out to be toast too. He was on a VERY strict budget and we couldn't find a set of original heads anywhere close that were worth saving, so we started looking at aftermarket.

We discovered a set of cast iron heads at Summit Racing (P/N SUM-152123) and started doing some research. Come to find out, that head is actually manufactured by Dart and doing a Google (or Yahoo) search showed it to have some pretty good feedback.

We took a chance and got a set and I have to say I was impressed. For the money, they run just as well (if not better) than the stock Chevy heads and so far (it's now been 3 years), they've held up well.

Note that the cc for these heads is 72, so more than your original heads so they may not work for you, but my real point is that don't overlook the Summit "house brand" heads since they're not manufactured BY Summit, but FOR Summit by various manufacturers. As another example, the Summit SUM-162109 aluminum heads are manufactured by Trick Flow. We thought about going with these since they meet California emissions regulations, but they were a little more than he had to spend (and his truck is off-road only, so the cast iron were fine).

I don't know which of those two would work best in your application as far as Flow/HP,
but taking 60lbs. off the front of the car is always a great idea.

Since you already have 11-1 compression, don't use any chamber smaller than the 64cc you had.

Aluminum heads are only $200-$300 more than cast iron. IMHO it's foolish to not get aluminum.

These E-street heads are excellent. The only ones I like better are the 170 vortecs, but they require a new intake. The 170's are used on edelbrock's crate engines up to 440 hp. An awesome street head for torque.

Re: Replacing Camel Hump heads IE180 or IK180??

Bob,
I would decide on aluminum vs cast iron first. Then call Brodix or Dart or whichever manufacturer you want and ask them. They know what their heads will do more than 99% of the people on here. They will steer you to the correct choice.

Re: Replacing Camel Hump heads IE180 or IK180??

Thanks for all the insight.

I called Dart yesterday afternoon and was recommended to go with their SHP aluminum heads. I also did some looking at the ProFiler 185cc heads and also found they got very high remarks from a lot of people. I did look at TF's offerings but they seemed slightly more than what I want to spend (remember, replacing these heads wasn't planned for).

I also noticed that Jegs sells Profiler heads under their name for ~$125 (if I remember correctly) cheaper than buying from Profiler or Summit. I just don't like the "jegs" on the end of the heads....don't care id the camel humps are there or not, but not "jegs". Just not sure if it is engraved or laser etched and how easy it would be to cover/eliminate. Also not sure if they assemble the their heads for if they buy them per-assembled from profiler.......

Not interested in the vortecs as I like my 80's vintage intake, plus I need the oil fill tube because I use and prefer to use the old scripted Chevrolet valve covers.

Worst of it is, I need to make a decision soon........

thanks for all the insight as to how i should spend my money.....LOL

Re: Replacing Camel Hump heads IE180 or IK180??

Having a 327 as well as the 462 heads , Comp 270H cam @ .470 lift , then 1.6 roller rockers bringing the lift up to .501 and wanting more power. I looked at the reviews for several heads, Edelbrock performer RPM as well as the others listed above. .After reading a an article I went with these from Jegs. https://www.jegs.com/webapp/wcs/stor...rsistYmm=false

They pull the torque curve down lower which the 327 needs, had better mid rpm HP then the RPMs and were within 5 hp of the RPMs. I installed them 3 weeks ago. I no longer have to feather the clutch, the engine has a very nice growl that it didn't have with the 462s. The throttle response is great as is the 0-60 times. These heads made driving that much more fun. Wish I'd have done this swap much sooner.

This is the article that I looked at. The heads shown are 180 vs the ones I purchased at 195cfm.

I was looking at the 180cc version of those Jegs heads. https://www.jegs.com/i/JEGS/555/514002/10002/-1

The "jegs" on the ends of the heads, is it engraved into the head or is it laser marked?

I have Edelbrock heads on my BBC and filled the "Edelbrock" script with bondo and painted them orange. An expert can spot the difference between cast iron heads but it still looks stock to most people.

They are engraved maybe 1/16"
