93625 171 Small Block Mopar Assy Promaxx heads

I purchased a set of there CNC ported small block heads. Being that I am using a Lunati can, solid roller, the springs were never checked but simply swapped and it was easy enough.

Often I read the listed height of installed spring heights are not at what is advertised, but taller. (Example; 1.800 listed, 1.900 as delivered.) ProMaxx uses (IIRC) PAC springs. I would follow the cams manufacturer’s spring recommendations or a set from a other company like PAC that are the same or super close. Reinstall at the needed height.
