I forgot to mention there are alot of ways to achieve your final compression if things don't go exactly as planned. And another thing don't get caught up in an exact number. Find a good a good cam that fits your needs and then get as close as possible to your desired compression. As a general rule you want a 8:1 dcr for pump gas. So get your calculator and see what compression you will need to achieve 8:1 with whatever cam you pick. And if you need it have the formula to get the IVC for the calculator.
