When you can get fully assembled ready to run out of the box aluminum heads for seven or eight hundred dollars sent to your front door there's reason for alarm....
When you can buy intake manifolds for $135 and then wait a few months and sell them for 185 plus shipping that's a good deal or when you can buy heads for $700 and sell them for a thousand plus shipping a few months later that's even a better deal.... I've seen it done all this last year on this forum...
