What kind of use are you going to be using this engine for mostly. You mentioned lightening up some things, the Crower rods are going to be close to 150-200 grams heavier per rod that the stock rods are. So adding a heavier rod to get a lighter piston isn't going to be big benefit. However, the Crower rods will make your wallet lighter(LOL). Also, a set of Venolia flat tops are $72.52 ea., and for that price that can put the valve pocket where it needs to go and any ring spacing and package and compression hgt, you need.
