Default LT1 valve train on TBI motor?

I'm pretty sure that this will work well, but I just want to confirm. Will the valve train from an LT1 work with a TBI from a truck with vortec heads? How will this perform as far as power increase?

what parts specifically are you planning on swapping?

springs, pushrods, cam, lifters, rockers?

Basically everything. I just didn't know if the springs from the lt1 would fit on the vortec heads. Also I didn't know if the pushrods were the same length as the tbi pushrods. Is this swap even worth the time?

probably require different shims as I know the iron and aluminum lt1 heads require different ones and a vortec head is basically a foreward cooling bbody head

might be a little gain, like the equivilent of when people used to put "rv" cams in cars but nothing worth much hassle unless you got alot of free time and free parts
