Now that I have my compression ratio dialed down to roughly 9.5:1 with the 670 heads, I will be looking to complete the build and order the parts. I know I will have some additional hardware and expenses for the springs, valves, gaskets, crankshaft machining, camshaft dialing, balancing, etc. I will be using an M21 4 speed transmission with an 8.2 BOP posi rear end with 3.08 gears.

Does this seem to correct the "Mis-Match" of parts from the initial post? Also what would be the estimated HP/TQ from this build?
It also appears that going with the Edelbrock 61599 aluminum heads would be something that I will consider as well:
