Thing is I'm not running any spring pressure to speak of. 135 on the seats is whimpy for a hydraulic roller ,, that's dam near solid flat tappet territory.

SBC doesn't need a ton of pressure anyway the valvetrain is pretty light. Not like a Pontiac or BBC where I typically run 150-160 seat pressure on a hydraulic roller

So to have sewing machine noise and also have one bleed down after sitting a bit with these little springs doesn't speak to well of the evolutions in my eyes.
