SBC heads with weird valve seals

hello all

I bought a 1986 GMC K15 which has a mexican reproduction 350 which was rebuild recently

after inspecting the heads I found no valve seals and they won't accept regular 350 valve seals

I've tried many types and I found a set of stock 454 Umbrella style seals that fits perfictly



but after mounting the springs I found that they touch the seals even when uncompressed


what should I do ?
Replace the springs with something bigger ( wider ) ? stock? aftermarket?
try other seals ?

thanks
