Head swap questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Need some guidance. I'm doing a vortec head and cam swap on a basic 190 horse engine I bought a couple of years ago. I don't think I have 500 miles on it but I just want to get some more ponies out of it. Although I've done 95% of the work on my truck this is my 1st attempt at taking an engine apart.
1. I see conflicting info on reusing the head bolts, should I replace them? What sealant to use on them?
2. Cleaning the old gasket material off the block. How do you keep the material from getting into the oil & coolant passages.
3. Currently using TPI but thinking about switching back to a carb. Anyone using the Demon 625 & if so, how do you like it?
