It wouldn't surprise me at all that they have lost 20 to 30 Lbs. every where scope
I like to use 140 to 160 Lbs. on the seats and from 325 to 375 opened on both hydraulic and solid flat tappet cams for street use with stock valves, add a tiny bit more pressure(10 to 20 lbs.) on both for larger, heavier valves twocents


Cab, I checked my notes and I don't have the pressures listed. It was about 2007 when the heads were prepped. I was planning to use a hydraulic FT (XE284 I think) at that time so those were the specs provided to the machine shop to set up the springs.
Dwayne talked me into switching to the solid cam, for which I am grateful I should add.

Thanks,
Mark
