where can I get some valve springs for an Isky 185G cam

[3W Hank]

I was just at Gardena at Isky.
I bought/find the cam Rons roadster told me was ’my’ cam, the Potvin 425.
I was hoping see the old guy there but he was told had a good day but unfortlantny I was there late afternoon so he had went home.
Idea was the 185-G has a installation height at 2” and 85 LBS.
It is maybe for a .400” lift cam and not .425”, so I cant get 85 LBS but my question to Mr Isky was that I has std 44 grams lifters and titanium valves 8 mm stem = light.
So as no ’real’ racing so should ca 70 LBS be all Ok here.
This technology I has no experiance off.
Anyway I bougt a set and I thin with tax 125 USD.
