I am looking at buying a head and the guy thinks that he has sportsman springs from DonM on it but has no proof and has no idea where they were bought from, is there any way to tell for sure by just looking at them?
They are used and were sold more than once, so no one knows for sure if they are sportsman springs, and i was just wondering if there is any way to tell just by physically looking at them.
Just check the spring pressures and compare to the chart on F1's site. You could atleast rule out them being stockers... I think installed height is 1.4" maybe?
