LS6 manifold and a set of 853 heads that flow 300 CFM @28" @ .700 lift (need springs) all for $1000

Do you think its worth it?

Idk. you need to know the flow#s from low lift all the way up. More than likely you won't be using a cam w/ .7 lift. The mid lift #'s are more important as is the runner size and the cumbustion chamber size. were they milled? ect. you can normally get an LS6 intake for around 300 -400 used so that puts the heads at 600-700. Imo I feel they are a little overpriced for bare heads exspecially if they are used. It sounds like it's just a basic clean up of the ports. You need to factor in head bolts, head gaskets, intake gaskets, valve cover gaskets, possible tb gasket,& ls6 collant lines.Plus plan on spending around 250 for a good spring set. while your there you might as well spend the 100 for new pushrods. You will have to do this if they have been milled. You gotta ask yourself. "Is it worth all of the trouble for the head swap?" Or are you going to wish you would have spent a couple hundred more for new proven performance heads that are fully assembled like ones offered from TSP and other vendors. Just my .02. Hope this helps.
