Anyone install Edlebrock aluminum heads ?

If you have the time and the space and everything it wouldn't hurt anything to take your current heads off and examine if the Pistons are down in the hole or if they're custom or stock. At the very worst you would be into it $100 in gaskets.. at that point you really only a water pump and timing chain cover away from pulling the cam out as well.. well you have them off you can take the valves out and do some home porting and there's plenty of how to stuff here right on this forum.. I'm sure 318willrun has videos on it..
