Some additional information for the forum.

The springs on the head are Manley Part No. 221424-16. The retainer found on them was tool steel and did not fit the springs. The retainers were loose on the springs not fitting properly at all.

According to Manley the correct retainer is a titanium piece that fits precisely this spring set. Please feel free to verify this with Manley.

Based on the all the evidence of the valve train not being in proper control I feel that it points to two basic areas: A)Mistakes in part selection (1. Wrong retainers, 2. Improper length pushrods) and B)Mistakes in the set-up.(1. Not properly shimming the springs to limit any tendencey for resonance. 2. Improper setting of the lash adjusters, thereby negativley affecting the geometry of the push rods vs the tail of the rocker arms.)

Anyhow that is how I read the report.
