Any one using these on a na car?
What improvements have you noticed? How much power do you now make?

Thanks

I have been running them on my CLK for two years. I can not give you an honest answer on actual HP gains becuase I had them installed at the same time as my original 2.3 L Weistec blower so I went from my 500 or so NA whp to over 600whp and can not see how much was attributed to the heads. I believe I had their prototype heads on my car. There are others running them as well. I know of one customer, (Lou Niellsen) that is running an NA set up on his CLK BS, he is running headers, a Weistec tune and the Wesitec heads but no blower and he was impressed with the gains he saw from what I gathered by speaking with him.
