I checked one of the ones here.
It was 140@the 1.820 installed height.

This is a 311lb/in spring.

I think it’s the same springs as that previous set I had here, but for some reason those heads came with more installed height.
(They went on a motor with a .480 lift cam.
If the springs were at 1.850 installed height, you’d have 130 on the seat and [email protected] lift, which is about how I remember them being.)

This set of heads does not have the 1.900 installed height that’s listed in the specs, and the springs are not 1.250” diameter.

I don’t know how it is that so many of these parts places can’t get the simple specs correct in their catalogs.

If I'm not mistaken this jivs pretty much with what you found. I know on the bottom of the page was some of the stuff I let him know about the cam and rockers.. possibly stuff on the upper right hand corner could have been things I was telling him about the Springs that were on the car... I believe the Crowder springs on the Factory heads were 150 and 340 but I had much more duration and much more lift.. but I believe the little note on the left was all notes from the speedmasters..
