My wife picked up my rebuilt heads on Friday afternoon. By Friday night they were in the shop. I pulled a few of the valves to show off the new stuff on the heads.
Three angle grind on valve seats with a 2 degree interference on third angle.
The old worn guides were machined out and new hardend cast iron valve guides where installed. There is such an improvement in the valve to guide clearance now. I fell much better about running these heads.
New intake (Perfect Circle) and exhaust valves (EngineTech).
Perfect Circle intake valve, part number 211-2561. The valve has 0.010 larger margin to save seat replacement.
EngineTech exhaust valve, part number V2307S. They have a Stellite face, recommend for turbo updated IDI engines. The valve has 0.010 larger margin to save seat replacement.
New valve seals with Teflon ring. These are supposed to last much longer with less oil leaking past the seal.
Passenger's side head.
Driver's side head.
