I ended up selling my rockers with my old heads so I will be buying new rockers. I was told to definately get 1.6 with the lower lift cam and it would pick up power. I will have to buy a intake so it looks like I will prob go with the 270 heads and the super victor intake. Any suggestions on rocker arms? I was looking at the comp ultra magnums but don't see any 1.6 in them. Do you think there is any chance possible that this could be close to the 800 h.p. mark?
