Ok, listen closely because this is the first time I'll have said this. Not that long ago a buddy sent me a link (no I don't still have it) to a thread where darkhorizon posted on CGP and a few guys added to it. Basics were that supposedly based on the square pad on our 1.6 rockers, technically when fully pushing down the end of the pad gave close to 1.8 or 1.9 equivalent.
With that said, I took a stock motor that I drove for months and tossed springs, seals and rockers on to it. There was more power. I didn't dyno, so I can't tell you any more than I'm not a first time modder and would be honest if I didn't feel a difference.
