I have 2 sets of these springs, these are the best ones they make and are the polished versions. They have been checked for seat and open psi. specs and all are in great shape. Low usage and guaranteed!!! Specs can be found at Manley.com for these to be certain you require a spring with these specs. I have used them all and found these are best by far and last much longer than the others. These were always used with spring oiler valve covers which aid in longer life and end of race power.
