Looks great to me! I play with Olds and tried the trick valve seat angles and now back to 45. I think with aggressive dwell square cams it leads to uncontrollable high gear problems, I even tried 250 on the seat. Also going back to cast iron guides, have learned bronze has different expansion rates and will tighten down. Good luck!
