Does anyone have the stock OEM valve spring values for max seat pressure etc?

My machinist wasn't able to find anything.

No luck in finding them.

I'm thinking these would fit

I`m unsure if they would physically fit without comparing dimensions, but the seated pressure is around double that of stock springs IIRC.

Unless you are running a fairly radical aftermarket cam and your cam manufacturer recommends those high pressures they will only lead to exaggerated cam & lifter wear, which is a major issue with these engines anyway.

That's what I thought.

I have a webcam grind #144 and they recommend running on stock springs.
