i just got these two milled stock heads from a guy who had the same ski as me both of them have a different dome size but he didn't remember what they were, i was going to bolt them up this weekend and see what compression they gave me i have perfect 150 compression in each cylinder right now and was wondering at what compression i should start running a race gas and if there was a way to measure the dome size
