To that end, I'd like to add this;
if you build with the thought that your cam might not be the exact one you want, then set the short block up in such a manner that you can go up or more likely down one size, and by changing gasket thickness, and or fuel octane, still have the Quench remain in the favored window, so as not to accidentally initiate a physical problem in the chamber, that could lead to engine damage.
This takes quite a bit of forethought with Iron heads, but it's not too bad with alloys; which, in my combo at least, were able to run up close to 200 psi; and Lordy that combo had bottom end and throttle response!
