Well,
I would of been the same price to have the head reworked on the 207 as I does rebuilding the 235.
The 207 is prone to head cracks and I had no clue what the lower end was like. It turned over freely and the bores seemed OK but you never know
I know now what I have with the 235. I'm hoping it will be more dependable and hopefully I can get a couple more miles per hour with the higher rpm's
