So I wanted to look up a water manifold remembering Indy used to make one for the big blocks and I came across this in the clearance section:

Stage VI heads and intake for $795. Looks like a deal of a lifetime to me. Thought I would pass it along for anyone wanting to upgrade to aluminum heads. Pic shows bare heads, but it seems like a great starting point.
