I don't think Super H sleeves will fit, but there are rebuild kits with stepped head or fire crater pistons that will give the H about as much power as a Super H flat top piston engine. From your statement about volumetric efficiency, etc, you obviously know more about engines in general than I do. But, under load, I think you are going to get detonation with 87 octane at 9.0 to 1 compression. As you know some (most?) modern automobile engines have an automatic spark retard that allows them to have higher compression and still run on low octane gas. Of course the H does not have that and I don't think the magneto, or distributer, if your 43 has one, will allow enough timing retard to let it run at 9 to 1. Also IH made kerosene, distillate, and gasoline heads. The gas head, of course is highest in compression, but I think the kero and/or distillate were as low as 4 to 1. Post the part number of your head, and someone will look it up for you if you don't have a parts manual. Now, having said all that, someone that is into tractor pulling will probably shoot me down. So be it.
