Valvesprings are not related to the short block.
Likely, what happened is that previous engine failures have contaminated something in the engine that is not being properly cleaned or there is sealant in the front cover. At this point, In my opinion the correct fix is another new short block, new heads/cams, new oil pump/pickup, and new front cover.
