desperatly need engine help

so most of you agree empty the lifters an put in the new rods and i should be ok? and about the cam, its what came with the block and rolling assembly, im hoping its not as horrible as you guys are saying. lol, im running nonported 340 heads with 9.5:1 dual dish forged pistons .040 over. will it be all that awful?
look at it this way if you have never had a cam that works well
in a particular combination you will never know what your missing..
man im hanging out here making trouble today ...I realy must not want to go
pull that trans pan and play in the fluid!
