Great L98

Hey guys, my first post/thread on this site, huge place. Anyway, I had a few questions about engine rebuild options.
Have an 85 Vette that's been sitting since 2002. It's been undergoing a slow very slow tear down and rebuild of the whole car. Well, the teardown was the fun part as it was interesting to get my hands dirty turning wrenches and removing that old crud off the car that had failed because of old age. Had a new crate 350 installed in 2001 when the old L-98 went boom. Unfortunatelly, not even a year after the new engine was installed, trouble struck in the form of a faulty alternator. I didn't know about it at the time but when I did some checking and realized that was the cause, the car was already completely disassembled. :bang: Rookie mistake on my part.
That aside, the 350 crate engine is brand new with not even 5,000 miles on it. While it's sitting out of the car, I removed the heads to discover that the pistons were encrusted with carbon deposits and scaling had developed in the coolant passages. :barf:
Long story short: Thinking about a complete teardown and rebuilding of an even stronger running 350, when the thought of a 383 stroker sounds fun. The only things I really know about the process of increasing the displacement is through boring and stroking. For my 350, I was thinking that the increased stroke would due? A 383 crank along with a notch or two in the block itself to allow clearance for the longer crank. If I upgrade to a 383, ditch the iron heads for something better? An upgrade of a cam is probably a no brainer as well. Personal labor on this project is not a concern as it's just that, a project for fun. This should be a breeze compared to what I've already had to do.
I have many more questions which I'll post up later, thanks to all in advance.
