Hydraulic roller cam spring pressure?

[quickt]

The 99838-12 can be shimed to work. They do suck as they dont fit for one and they will lose thier tension in a street car in just a few short months. The K-750s set at 125-130 on the seat will last for years. They are drop on but must check installed height. They will work with the stock retainer. Been down this road before dont waste your time calling tech lines as they dont have a clue. 110 on the seat is all good until you add in boost and a few street miles then it is just not enough spring.

Thanks for the replies guys. The first thing that I did was call the tech line,sat on hold for 20 minutes,and just thought that when someone finally got to me he would just read off the same cam card as I have & tell me those are the right springs.
He did not know anything about the affects that a boosted motor would have on the springs, so he asked his supervisor & his reply was that higher spring pressure would shorten the life of the
lifter. (there's a surprise)
Thats why I posted here .
Thanks again. James
