Could I use 71 351C valvesprings on my e7's?

I bought a fresh set of valvesprings to use on my 351C 2V d12ae heads and now with the project shelved, I am wondering if I could toss these springs on my E7's with my 1.7 RR's and have them work properly? I'm not sure of the dimensions since I havent had the heads off my car in a while.

Would too much spring pressure hurt performance? I would assume that the 351C springs are stiffer than the E7's. Would it cost me HP?
