Id rejet the H carb. The big M style carb on a low rpm/stock engine wont make much difference,,,, in fact, Ive seen the H carb out do the M carb on stock H's on the dyno. They had the same 540 HP, but the little carb had more low end torque. But, if you do go with the M style carb,,,, look for a 23 venturi,,, which is for the Super H-350 tractors. Its a little bigger than the H, CFM wise,,,, but keep the air flow restricted to keep the air speed faster in the manifold. This helps low end power, too much air and it will fall on its face under hard pulls faster than a smaller carb setup. Want more power,,, try E85 ethanol. You cant run it straight, but you can mix it with pump gas and see a gain. each tractor has its own mix,,, and its based off the cyl pressure to determine the proper mixture. Chad ChadS3@hotmail.com
