can you use the cheaper bearing for a head and cam car without spray or boost, or would one still be better of going with the moly rings and the tri metal bearings

car spins to 6200 head and cam, balanced stock rotating assembly, nothing special really

 

The work it takes to install them makes use of cheap rings and bearings illogical. Also, even a stock LT1 is a high perormance motor which would mandate decent parts. They aren't very expensive anyway, so get some good rings and bearings.
