I never understood why doesn't somebody just make an Aluminum W2 (As cast or CNC ported) with the shafts and offset rockers available as a Kit? Surely the Batten Sand boxes must be around somewhere?

FWIW I had my W2's thermal barrier coated in the chambers, Valve faces and exhaust ports, I wasn't too worried about weight for this one though.

In retrospect I should pull the 414 alum head motor out of the Rocky and put the 440 W2 in it's place....The rocky could use 40 pounds over the nose to help it not wheelstand....plus I have a Holley Pro Dommy Tunnel ram I could use AND STILL FIT IT UNDER THE HOOD
