Here is the problem I run into after buying my Farmall H. I pulled the head because it needed valve work and when I did I noticed it had IH Firecreator pistons. I remembered from when I was young helping my dad overhauling our Super H that the instructions that come with the Firecreator sleeve & piston set says that you must have a high compression head when installing the piston set. Well not thinking anyone would put in Firecreator pistons without the high compression head, I diden't check the serial nr. of the head to see if it was high compression or not. After getting the tractor running, I could not get the engine to idle without laboring and missing. I rebuilt the distributor and carburetor, rechecked timing but would not change the idle problem. After putting the H on a dyno at a antique tractor show, it showed low on hp. so that got me to thinking I had the wrong - low compression head on my engine. After taking the valve cover off and checking the serial nr. I found out it was a low compression head. I replaced the head with a head from a 300 and now it idles perfect and has great power. Another good thing about a Super H, 300 or 350 head is that they have rotors on the exhaust valves if you are going to do hard work with your H. I had steel seats cut into the head for the intake valves also for burning unleaded gas.
