i forgot if it was possible because of the valves location on the head but couldnt u just shave and deck the head alittle bit to raise the compression, i know we do that on my motorcross bike for more compresion but that is a 2-stroke. i dont remember if it was possible when i had my engine out and apart. the valves might be too close. if it is possible, it would be alot cheaper than pistons
