I hear you but you can’t be a cupcake about it either. There is a lot of knowledge on this site with most willing to share info. If someone tells you you won’t see a difference in performance if you trade off your ported Edelbrock heads for a set of TrickFlow heads and you are running a 550 lift cam don’t get upset.
