seems like middle of the road spec raitings there getting towards the higher end of things. id still upgrade the rods and springs doing any type of cam work on a ls motor. our springs are weak stock, especially going with a bigger cam and larger lift
edit: if you already have the 243 heads then id use them, just beef em up a bit.
