Does anyone know where I can find a set of steel rocker shaft hold down blocks for W2 heads?
Thank you.
 
Steel? Not aluminum?
Yes, steel.. I'm having my stroker 360 with W2 Econo heads inspected and my engine guy noted there was too much lateral rocker movement on some of the rockers and a couple of the aluminum hold downs got scored, so he's recommending steel hold downs.
 
Can’t you put a hardened shim used to space your rockers between the rocker and holddowns. Summit stocks them.
 
Harland sharp makes them

The best fix is to narrow the exhaust rockers and put Torrington bearings on both sides of the rockers.

The side load of the offset intake rockers is insane and it's very difficult to keep the galling down.
