The rocker ratio option sounds like a very good idea. I may very well try that if I switch out the heads. I could go ahead and find me a set of 1.6 ratio and set the heads up with them. I have always thought this was an expensive option based on what I have seen, but I was always looking at roller rockers when I looked at this. Since my cam is a solid lift I would have to find the right set. I have seen ugly reviews of some of the sets vs others. Some like the Harland Sharp seem to be preferred, but they can get pricey. I will start to keep my eye out for a set.
How much does your cam specs change when you go from 1.5 to 1.6?
