OK guys, quick question that a search did not give me a clear answer. My son and I are building his first car. It is an 93 Shadow. The block could use some work so while it is at the machine shop I am thinking of installing flat top pistons for him. I know TBI motors will never be drag racers > but I wouldn't mind giving him just a little more pep in his 2.5. Would you guys recommend flat top pistons for him? Or would just shaving the head some do just as well? Really, I have no issue leaving it bone stock, I am really just curious if the extra hundred bucks would be worth it or not.
