stock appearing aluminum head
If these happen it would be a good option for many applications. Chuck
Note on these heads (from what I have read in the network54 forum). The bottom of the intake ports are higher than the stock 4v heads. While a 4v compatible manifold will bolt up and work, the air will hit a 'step' where the port is higher on the bottom. This will have some impact on the performance (I won't guess how much). You can either stuff your ports to get them to match or, my understanding, is he will open the ports to match but notes that the flow rates won't be the same. Make sure you understand what you are buying.

I plan on getting a set of these heads so I am not trying to 'bash' them. Just be sure you understand how they will fit into your overall build.
