Thoughts on accepted aftermarket heads for 350?

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.
