From what I've heard for about $400. for vortec heads and $250 for an Edelbrock ,you can still use your carb,you get the best bang for your buck in increased performance. You could possibly find a good set of 194's around or older double hump heads for a couple hundred and use your own carb/manifold.Going the 202 route isn't really worth it for what you pay and get for your money in comparison.
