with heads--- of course aluminum's are more pricey then cast... but worth it.
a cam--- cant wrong with a custom cam... Comp and Crane have nice cams
Intakes--- there soooo many to choose from.
my mods in sig (h/c/i)--- cast heads $1100, custom cam $850, intake $545--- port work-- $500'ish
all depends what you want, and what it's built for...

There isnt' a best combo. If there was than everyone would be running it. If stock bottom end i would suggest the TW's or afr. To get the most out of combo a custom grind would be best but be sure of what you want when you order it.
