430 John Deere

Can you use dome type pistons in a two cylinder 430 engine if so where can i buy them?

how much compression is desired ? tractor pulling ? It will need the worn cam and followers re-ground as well.
All fuel was 5:15 to 1, gas 7:00 to 1 and LP compression info is scant to find .
There are four different part numbers for cylinder heads . With three variations in castings .

The gas engine in the 440 industrial had
More power than the agricultural 430.
