Anyone here using the cast iron heads in there fbody LT1 setup? I Just got a motor from a 95 Impala for dirt cheap and i was curious, should I just leave the heads alone or put the aluminum Fbody heads on it. The car is just going to be a cruiser not a strip car at all. Just a nice daily driver. Also whats the differance in MAF sensors on the Fbodies and the IMpalas can i use that MAF as well.
