Thanks for the responses.

I was mainly wondering about some others here mentioning that floating the lifters will bend push rods. I don’t see how that could happen without the valve hitting the piston and if the valve hits the piston I would think there would be other more serious damage.

My cam is about .550 lift and 230 X 236 @.050. I have checked coil bind and I have anywhere from .050 to .080 remaining. I ordered Manton custom length push rods and the pattern on the tip of the valve is good. That also leaves about 3 threads of the rocker stud exposed below the rocker arm. It all looks good.

I plan on pushing the envelope for RPM and wanted to know the dangers of hitting the edge of valve float. Obviously I won’t be holding it at that RPM, but the valves will probably be floating a little bit before I am able to sense it.
