Iron Champion Head Spring pressure too High

[wickedtt]

Is Champion Iron Head Spring pressure too High?
I emailed them and was told the Closed pressure is 95# - 100#
Open pressure with a .460 lift cam is 280#.
Has anyone had any problems with them?
I'm using the flat tap 206/206 comp. cam and i'am worried about wiping a lope because of the open spring pressure of 280.

Open pressures in excess of 360# require the use of roller tappet bodies made of billet steel.

Well everyone is always saying the cc980 sre good but there open pressure is only about 229#

Cam material/heat treating process is just as important consideration.

if you have to lite a spring pressure, you will have harmonic vibration witch will make you lose power. Bose
