I have the Crane conversion kit on my F150 with a 358ci engine with p-heads. It sees 5500rpm quite a bit (it's a mud truck). They've been on it for 4 years, and not one problem. I wouldn't use them if you plan to spin it over 6000, but under that, you'll be fine.
I ended up with Crane Energizer Rockers. I bought a set of Scorpions, but ran into a clearance issue with the conversion (side clearance). My local speed shop let me return them for a set of the Energizers. They worked out fine.
lift means nothing.......it's all on what lobe profile is on the cam, the ramp rates and or how aggressive they are that determine what springs should be used and how much closed pressure and open pressure there should be......what is the powerband of the cam?? if you have not tested the current springs rate, open vs closed pressure and compared them to cam specs then you need to do such......and please don't say but tfs says springs are good to xxx lift, I junk the factory springs right away when they come on new aftermarket heads, cause they are mass produced weak crap
