Any gains adding 1.6 rockers to stock 273?

I didn't think you were braggin. Brag all you want. lol All I am trying to get across is, you're lookin at a BIG expenditure for a SMALL gain and possibly NO gain. Hell, if you're dyin to spend 300 bucks and want a BIG bang fot the buck, put a little more with it and get a 150HP Nitrous plate shot.
Best advice all day there
