I just saw this post... most likely you need more spring and that may fix it,if does'nt have any bent valves... If it was mine, I would throw the hydraulics away, put solids in with .003-.007'' lash...
strongest pushrod,adjustable rocker and enough spring pressure..
I know saying things like that I will have LS'ers telling me how stupid I am.....but thats OK....

Agreed with you Mike. If a solid roller lifter is an option in a performance based combination - I would never choose to run a hydraulic.

The valve springs on the car were conventional spring with damper non adjustable rockers. The springs were a little weak...I wanted to go with single conical spring like the hemis have,but my engine guy said they're too tall for your valve stems, so I deferred to his judgement and going with new PAC springs with dampers. I only need to get another 4-500 RPM to get to the finish line. I plan on buying a "good" set of heads in the hopefully near future and will set them up with better stuff.
