Cab,
I measured/shimmed each spring to the installed heights mentioned above. I do not have a pressure gage so the 153lb average is per the spring chart. (1.800"=160lbs, 1.825"=150lbs)
My coil bind clearances are .078"/.088" pending lobe design. My seal to retainer clearances are +.100" minimum. I did "try" to check rocker ratio last Winter when I installed the rockers, but I was having trouble with the hydraulic lifters bleeding off on my final setup. If I remember correctly, I was within .015" of the actual theoretical lift when the lifters were giving. So they are close. Plus I have the B3R geometry kit which helps gain a lot of the lift back too.

Thanks Cab!!
