I was looking at them and the Dart look to be the best without going to the aluminum heads. We already found quite a pick up over the stock castings.

Is/are the runner volumes going to be an issue.

I was told you have to add 50# if you run them.. Just getting hard to find good cores for certain heads.. Mainly wondering if anyone went that route yet

I haven't heard anything about the runners yet. It depends on what class you run for the weight to be added. It's a 5 hp penalty across the board.

Unless you are running Super stock and filling the ports none of these heads are going to meet the port cc. numbers. You just cannot mill enough off get from 175 to 161 cc . I know they are showing 172 cc but check 174/175 cc. Rick.

Then if you can't adjust the runners because that's illegal and you can't leave them as is because they have to reflect stock runner numbers how would they be able to kick you out if you are running the spec head they approved?

The Edlebrock heads are 185 cc’s on the intake runner. Who approves this stuff?

Great thing about aluminum. You can weld it up, reprofile it, and cover it up. It will look like new and you probably pick up 30 hp at least. You have to do
something to keep up with the Mopars.

Question who actually submitted all these heads to NHRA or did NHRA pick them out. All these heads cc way to big to be used in stock.
