Anyone knows the stock valve springs specs (seat/open pressure, rate, style, dimensions, etc..) gen 3 or 4

Thank you

When I need this info (don't have it anymore), I just bought a spring from the dealer (<$10) and measured it.

Yes I know but I thought that information was easy to find on internet. Looks like it's not, I can barely find any information on the stock camshaft (0.544'' lift?)

Well, at least I have the flow data of the heads (stock & ported)

Available for gen 1, 2, 3, 4:

Stock and even ported heads from the Gen4 clearly doesnt benefit from lift over 0.600'', but for the gen3 it does. Assuming the flow data is good, of course..


I'm just curious about all the specs of stock camshafts, valve springs, etc... of gen 3, 4 and even 5. But I can't find it anywhere.
