opinions wanted on valve springs!!!

Long story short, I ordered a Comp Mutha Thumpr last night for the 360. I was comparing Comps spring recco vs the Trick Flow springs I already installed on the heads. Comps p/n 995-1 specs are 1.437 outside diameter, coil bind at 1.02, 402lbs/inch The new Trick Flows I have are 1.495 outside diameter, coil bind at 1.1 with a spring rate of 355lbs/inch. Can I get away with these? Input appreciated in advance!!! Thanks Nate
