Scoggin-Dickey offers a Vortec conversion kit for under $1100 (
http://bit.ly/2nkIkC3). It comes with an Edelbrock Performer manifold, heads, rocker arms, gaskets, and all fasteners. Using the supplied .028" gasket with your Goodwrench will give you compression in the 9-9.25 range, which is ideal for a 204º-210º degree cam, which all the manufacturers make. Combine that with a good set of small-tube headers and your Q-jet, and it will make a great daily driver.
