block/head combo questions

[seanrolandwood]

so before i get the how the fu@k do you not know this sh&t already comments, sorry I've never really messed around with anything other than direct replacement stuff this truck is my first venture into doin stuff on my own as well so i need to ask the painfully obvious stuff so here it goes.......
i have a run of the mill 350 010 block and i need new heads it's currently is running an old set of 3932441 heads 1.90 1.50 74cc heads i want to put vortec heads on as i hear they flow well... from there the info gets confusing as 1 person says you need this while others say another thing so can any one lay it out for me....not well i hear this and so on maybe someone whos done this already...
basically i need to know what all I'll need to do this correctly im not into cutting coners: specific intake? cam? year of heads that work? and anything im not thinking of thanks for any and all help
