Add hotter cam or Add hotter head ?

Some of us like to chat about cars..... Toolbox talk so to speak :) Scenarios can be fun, and somebody could learn something or even get an idea for their present car.
I pressed the unwatch button but you quoted me back in here so the truth of the matter is I like trying to make a decision or maybe even a future decision and helping other people wrestle with the best case scenario decision when they're on the edge of one way or the other, but fantasy talk isn't my thing..
