Setting installed height

Just to finish up this thread, these heads went to my machinist for a check up and a valve job after the comments and recommendations here. From speedmaster they had .060 worth of shims and no spring seats so we ditched the shims and ordered .060 seats, he cut a new 3 angle valve job, and installed Manley Extreme Duty exhaust valves (turbocharged marine app). He said overall they looked ok but the attention to detail could have been better in thier assembly. I bought these on the Black Friday speedmaster sale so all in I’m at $1500 for the top end and $953.82 to have the heads gone through and some parts replaced. Thanks for all who chimed In on this thread.
