      I have never seen any evidence that the AFR street eliminator heads are not fully ported. You may be able to buy the street heads with no porting, but I bet they would be less than $1500 a set. I am saying that at $1500 a set the AFR street 195cc heads are fully ported. Can you show me the opposite?

      Also, are you saying that they are lying in the article when they claim that that is a picture of a street eliminator head for $1400?

      Even if $300 put the dart heads at the performance of the AFR heads rather than, you are still spending $300 more for the same performance. The prices I got out of Jegs.

      Here are the AFR street eliminator heads out of Jegs for $1464 a set. Also, jegs claims that "each head is 100% CNC ported". Under more details it claims

      100% CNC Ported Combustion Chambers
      100% CNC Ported Exhaust Ports
      100% CNC Ported Intake Ports

      http://www.jegs.com/i/AFR/033/1034/10002/-1#

      Here are the Dart Pro 1's with no porting for $1386, it should also be noted that they offer a 72 cc head for $1200 a pair.

      I know that you dont trust any of the evidence I have given. I dont mean to be rude, but you have not provided anything to substantiate your claims about the AFRs not being fully ported. Do you have something I can see that supports your claim about the AFR heads?

      I am saying that I called out the comparisions of as cast vs. cnc ported heads and the AFR said they made more power. Well, yeah, they are worked. So my point was the comparison wasn't fair. So we can agree then that any comparision with as cast heads is not a fair comparison rendering all of those past comparisons worthless. Just want the OP to know what it is.

      No, I am saying that the comparisons that have been posted that many rely on aren't fair, based on your criteria.

      Even if $300 put the dart heads at the performance of the AFR heads rather than, you are still spending $300 more for the same performance. The prices I got out of Jegs.
      Who's to say it's not better for $300? If he took stock Chevy heads and went to RFD as I posted he'd probably get KILLER results for less. Again, is this about money or performance? How about my IK example? Take the $900 IKs and get them worked, just over $1500 and I guarantee better results if you go to the right guy. Is that an option?

      Right, but on what basis do we believe they would be better for the OP? Not enough information. Using HP as a measure of what is good is down right stupid. I can show you lower HP cars set up right that will out right SMOKE a higher HP car. What's your point? Let's even concede that AFR gives more HP. IS IT RIGHT?

      You only provided links from a catalog that the heads are ported, no evidence of anything. I agree. They are ported. OK, now what? If I understand your position correctly, there is no need to look at any other head for any application in the $1500 range. I hope the OP understands the folley in that position.

      hat claim did I make about AFR? I am saying they are a GREAT PRODUCT. I am only saying there's more to consider and the OP deserves to get all the information.

      If I came here and told him he needs to look only at Dart because Dart uses Spinton and Wetflow technology therefore they are superior, that would be bias. What you are doing is bias, and I am simply pointing that out.

      How's this. Any head not designed with wet flow technology will not perform as well has one designed with wet flow technology ported or not? That is Dart's position? Is it any more or less valid than any other manufacturer? NO IT IS NOT? They say their wet flow development can suspend more fuel and provide more power. See, the difference is I am admitting that is Dart's position and is only as good as the source. You however are drinking the Kool Aid and substituting manufacturer position as fact. THAT is what I have a problem with. And that is what is wrong with the internet.

      I appreciate the contructive ciritism. Thats what I want to hear. Thats what helps me learn. I would like to use a cast crank cause I have good one. I have stock rods in good shape to. Might as well use them. The only Thing I need is pistons. So your recomending hyper pistons and i can use the rods and crank as long as i keep my rpms at round 6500. as far as the cam, i dont need the thumpr, i was after the lift mumbers. I dont know alot about LSA and a little about duration. I do want the good sound but I want it to run as good as it sounds. Im not after a lopey idle with no power like alot of people. So hear is an idea of what i want to use:


      Crank: Stock cast 350
      Rods: stock cast 350
      Pistons: KB Performance Pistons 9901HC.030 KB Claimer Series Hypereutectic Pistons
      Heads: AFR - Airflow Research 1034 AFR SB-Chevy Street Aluminum Cylinder Heads
      Carb: Holley 0-3310S Holley 750 cfm 4-bbl Carburetor with Manual Choke
      Intake: Edelbrock 7501 Edelbrock RPM Air-Gap Manifold=
      headers: Hooker Headers 2116 Hooker Headers Super Comp Headers=

      Seems like a pretty good match. But the intake ports and headers are pretty big, so using enough cam to take advantage of the heads and header sizes will put the powerband up right against 6500 rpm. You sure you couldn't "get by" w/a bit less intake port volume and primary header diameter? You might be giving up some top end HP but you'd gain everywhere else.
