I have a flat bottom boat with a 1962 oldsmobile 394 .030 over, solid lifters, stroked. my problem is finding a adjustable rocker, ball adjuster. Was solid lifters stock 0n the 394 ?

 

The only solids for 394's I have seen were from aftermarket companies long ago. They used hydraulic lifters. However check out Ross Racing Engines as he produces new adjustable rocker arms and any related part your looking for
