Aluminum Head Identification

Any head that gets even a little serious starts to get pricey. MoPar or Chevy, the price goes up!

Inexpensive rockers are on limited heads like an OE or Edelbrock and the like.

The W2 & 5 heads share rocker gear but, low volume keeps prices up. A 2 or 5 head fully ported will out flow the Edelbrocks and shine when you out them to the test. The performance gap between them and the Edelbrock head is currently to narrow to justify making the move to them for the most part. With the introduction of the Victor head, well, the plug has already been pulled at MoPar for the LA stuff. Nothing more to say there.

Now the 2 & 5 are discontinued. You do them for nostalgia or for a final MoPar flag wave!
The W9 is still an option worth considering for racing.
Or us totally nuts street guys!
