vortex heads

Hi, I'm Tom.
I bought a 1986 chev crew cab with a 5.7 liter engine, with 89000 mi. The engine smokes a little only on crankup (valve guide seals) and the lifters are making noise. I was thinking of replacing with vortex heads. Will this give me more power and fuel efficiency? Will I need to replace the 4 bbl. intake?
Thank You
