i rented a valve spring compressor tool from advanced auto parts because i wanted to take the 105# springs out of my old heads and put them in the heads of the used engine i just bought from the junkyard. i did not want to remove the heads because i did not want to have to replace the head gasket and bolts. here is what i got, pics below.


This is the the engine that had the 105# springs, both heads have been removed.


these are the used heads that are on the engine still.




now, here is what i rented at the store.




what do i do?
