This morning I`ve got time to go through them to search for the problem.
Result: I find the outside spring in cylinder 6 broken. The inside spring and damper are ok.
Next problem: Which spring do I choose as replacement? No number or ident. signs can be found at the broken spring.
Spring measures: OD 1.540", Length 2.470", Length in engine with closed valve 1.850"
SBF 302, FMS J 302 Alu heads, Comp CAM 31-760-8/288R valve lift 0.586"
Regarding the recomanded springs mentioned by Comp Camp, not a single measure of the installed springs corresponds.
Some proposals are welcome.

thats a solid roller cam....i would look deeper, before planning the attack.
check out the lifters, if you don't know how many miles are on them i would replace them now or you could have an even bigger failure in the near future. looks like that spring is too much for that cam....according to comps recom. spring specs.
like another poster said.." i would replace them all if it were mine"
i will have to second that......new springs set up right, #914 for that cam, and a new set of lifters as insurance
