not really, a shorter rod length can buy you more bdc dwell time which can allow you to extend the intake cam timing a few degrees with the piston in otherwise the same position at the closing point, without the negative effects of reversion. This where short rods power is made (cam timing), nothing really to do with the rod length or leverage itself. For the most part the engineers have made the right compromises in stroke and rod length. The V8 guys and magazines have over blown the whole subject into more than what it really is IMO. With long rods the wrist pin gets closer to the ring lands, rocking of the piston then effects ring seal more and reduces ring life.

If I put in a shorter rod and deck the head would this have the same effect as stroker kit?

No. The length of the rod does not have an effect on the displacement of the engine. Stroker kits do.

Engines with short rods tend to generate their power at lower RPM, and the higher piston speeds earlier in the down stroke tend to limit their high RPM output. With long rods, the reverse is true.

Chevrolet established long ago with actual research (under Duntov) that the ideal rod length would fall within the range of 1.6 to 1.9 times the stroke. It's probably safe to assume that they were not considering running at engine speeds higher than 8000 at the time, although small blocks have often exceeded that by 2000+. The rod/stroke ratio of a Gen2 YZ450 is 1.76. interestingly, and in the Gen3, they have offset the cylinder forward to simulate the angularity of a longer rod.

what you can do is look through the Pro-X site and see what rod matches up with the dimensions your looking for. probly hundreds of rods choose from. i put honda rod in a ktm by using this method.

Wouldn't screw with it until you've exhausted all other ways to tune power and have a way to quantify the gains (or losses).
