Yea, it says it up top. The W5 also needed end seals. IMO, this could be a Edelbrock copy - ish like type head. The benefit would be cheaper production costs. That is the one thing that drove me crazy about Ma MoPar's equipment. A bit pricey.
The W2 was reasonable. But the added cost of offset rockers and a oval port was just yet another thorn in the side of getting a budget racer out there.
