hey guys. so, i want my squish cut as i finally ripped my 250 apart for the first time since i got it off of my buddy. did the solder check on it and it came out to .069" What should the squish be set at? .40"? also, i want to be able to run mid-grade. so increasing my cylinder head volume will be a must.. anyone have any idea on what i should set my head volum at? info, opinions ect all welcome.
