Quote: If one mills the heads .060", must something be done about the pushrods? I remember in the old days people talking about shimming the rocker shafts to make up for milling. I believe some companies made these shims. Seems to me they could be homemade from .060" stock. Right?
By the way, is there a way to tell if big block heads have already been milled?
Shimming the rocker shaft is the HACK way to make up for aggressive head and/or block milling , shims are to CORRECT for INCORRECT rocker to valve geometry.
Measure the outer row of head bolts , under the exhaust flange , stock heads would be 1.000 plus or minus a couple of thou.
