Okay guys, here is what I am planning on doing. If the 350 does not need machine work than I am planning on buying the Sealed Power engine rebuild kit from Summit that makes 9.35:1 cr with 64cc heads. It goes for $219.95. I am also planning on buying the stock GM Vortec head kit with a performer intake from SPDC that costs $729.95. The only thing I have left to buy is the cam. What cam do you guys recommend? The stock vortec head kit says it is compatible with valve lift of up to 0.450". Should I go with the upgraded kit that is good for .550" lift?
