Get yourself some aluminum ones, if you can afford it. Get's an extra hundred pounds off the front of your Camaro, and lets you bump up the compression (plus they flow really good out of the box). If you want to look retro, fill in the aftermarket name brand stamp with JB weld (and sand smooth), then paint the heads to match the block.The moment somebody says to me, "This is very risky," is the moment it becomes attractive to me.

Racing Head Service makes a couple of dandy cast iron heads, #11301-02 for hydraulic roller with max 0.600" lift or #11301-03 for solid roller with max 0.750" lift. When I do a DynoSim, I always de-rate the flow by 5% just to remove the fluff from the manufacturer's published flow rates. Even with doing that, either of these heads make insane power for a reasonable price. Each of these part numbers is for the 320cc intake runner models.
