That's all well and good if you don't want the advantages- and hassle- of using Vortec heads. But you'd also get a hydraulic roller cam and 1-piece rear main seal. To me it's a step or two backwards to use an older 2-piece RMS block and if it needs "the works", it won't be cheaper than the Vortec long block unless the Vortec needs everything, too.
I had thought this was a performance upgrade, not just getting something into the truck that will run. At the end of the day it's up to you to decide how to spend your time and money.
