Cam and Valve Spring Question

In the middle of a 351W engine rebuild.   Of course I couldn't leave well enough alone.

My head were cracked so I found a set of rebuilt GT40P heads.
They came with a set of new trick flow valve springs # TFS-2500100.
Seat Pressure   115 @ 1.800
Open Pressure 315 @ 1.200
Max lift of .540

Ive also ordered a Cam Research Ski Cam which I believe has the following specs.
intake lift .49
exhaust lift .49
intake duration 278
exhaust duration 282
Intake duration @.050 216
Exhaust duration @ .050 220
lobe separation 112
recommended seat pressure 95lb
recommended open pressure 295lb

I'm a novice but It appears the valve springs have a higher rating than recommended by the cam card.    Will these work?     Of course I will call Cam Research but you guys are wizards so what do you think?

Thanks Jeremiah

I my opinion, that spring would be a good fit for that cam. With a .49” lift you are only get an open height of 1.31” (1.8” - .49”). At 1.31” you will get an open pressure of 280lb. I can show you the math if you want.

Too much open pressure is hard on the cam.
Too little open pressure and you might experience valve float.

Your only 6% less than the recommended open pressure (280lb vs 295lb). If you were zinging this engine past 6000 RPM you might have a valve float issue. But you are going to be maxing out around 5000 PRM. Also, being a little high on the seat pressure (115lb vs 95lb) is better than being low.

The next thing is to make sure the installed height of the springs is 1.8” Are you using the stock GT40P valves? If you are, pay close attention to the exhaust install height. I remember having to buy special keepers that raised the install height.

Thanks Everyone for the replies.   I called cam research with the specs.
They believe these will work just fine. They suggested I have the machine shop double check the pressure of the springs just to make sure.
