Hey Jim ,
   Besides valves and guides ,if you need them ,It is New Steel Intake 
valve seats you need in these heads ,if the
stock brass ones are still in it . They need to be cut with at least 3 
angles and 4 preferred ,if the replacement seat is wide enough, while 
doing the valve job .

  The bowl areas behind the seat need proper blending and a performance 
gain will be the result .
Of course there are other areas of Head work a used U-20 head may need 
in addition to the basic valve work .

This additional nec or optional work ,may need to be done after a person 
that is  Knowledgeable about Roadster heads , inspects and checks yours 
out .
That search will need to lead you to that person .  Good luck finding a 
shop in AZ., since mines in Texas ,I assumed you
didn't want to ship it .
Regards,
Steve
