or have they been repalced?

Hey Kim, Thanks
so i have removed the valves looking at the pure casting... look s very good.
especially the inlet port fits absoutely exact to the Intake sealing, bettet then my Edlbrock E-street heads did before porting.
here some picture after "home porting"

One Question, which valves and springs have you installed.. I plan to use the Edelbrock set:
93775 - Edelbrock Stainless Steel Valves Intake, 2.20 in.
9643 - Edelbrock Stainless Steel Valves Exhaust, 1.810 in
5771 - Edelbrock Spring Seat Cup Kits
5792 - Edelbrock Sure Seat Valve Springs
9644 - Edelbrock Valve Spring Retainers
9616 - Edelbrock Valve Stem Locks
