Nickle be nice now, I've seen posts where you have no clue.
As far as the compression thing. It will be argued forever but I can tell you 9.5 is very low compared to what I have seen done. Along with what these guys said to reducing detonation there is also the hot spots issue. If you wanna run high compression you gotta try to remove anything that will create a hot spot in the combustion chamber. There are some emissions control things that are simply hot spots that are supposed to help your engine, I believe ford had these on some of the 302s. CUT THEM OFF. They only get hot easy and lead to detonation. Also a flat top piston is less likly to have detonation then a dome because the dome will have more points that stick out and will get hot and keep the heat.
