W2 Race vs Econo Heads, What's the difference?

If you have the econo head buy the long valves and mill the stands down and use offset stands and blocks.

You do have options.

Without looking at the book, IIRC you can use the econo head up to .650ish lift. If you are using less lift than that, you can use the shorter valves and just buy a rocker geometry correction kit from B3 Racing.

You need to verify the lifer number first though.

Thank you, the heads are already assembled and I ran them for half a season last year. I was just surprised when the gentleman that's inspecting the engine for me told me they were the econo heads. It could just be a case of I misunderstood what the previous owner of my Dart told me.
