My application is very different than most. I don't need/care about more power. A tractor had 25HP. I have 3-4 times that with a bone stock 8BA. I want it to run smoothly, if it will idle very low I might win a slow tractor race
I want it to run cool. I am very handicapped in radiator size over a car or truck. Had a lot of cooling issues early on that I am now on top of, but cooling is marginal. I want to be able to drive in a parade or tractor drive. I have been on 2 tractor drives now and it did fine. So the only reason I might consider aluminum heads was if they would make it run cooler-but doing so would destroy the "1950 look" that I have tried to create.
From what I am hearing here I will probably leave it alone. I will do a compression test and if radically different will seek out an appropriate 8BA or EAB head to match.
