Joe, stay with a stock stroke if you want to crank it up past 7,000 rpm. If you run it over 8,000 rpm, you will need titanium valves, which are expensive and won't last long on the street. I would go solid roller over solid as you can have a much steeper ramp, less duration and more lift. You will probably need to change the valve springs regularly, but they are relatively cheap at under 250.00 per set.. I have a motor similar to cranky's but with yates heads. I keep it under 8,000 rpm and drive on the street as well as the track. Just make sure, regardless of your choices that you use a competent builder that will dyno and break in your motor. If there are any problems, they will catch it before they hand it over to you. I have had good luck with mine for almost 3 years, knock on wood. Scott
