Doc Fiberglass- The shop was recommended to me by a guy who had his 360 worked on. Personally, back in the late 90s I was new to doing this kind of speciality work on a motor, so I had to trust my fellow man on this one. I know the valves are new b/c when the machinist started to work on the heads, there were cracks in the valve seats that were fixed by going to the next size in valves. I know Manley valves were used, so I'm assuming so were Manley retainers.
The manifold has already been installed. I wasn't sure about cleaning the oil deposits b/c I wasn't sure what kind of damage would occur if the cleaning material & flecks of junk got into the cyl walls.
