Push rods

I don't know if this is the proper place to ask, but here goes. We have a stroked 440 with B1 heads, they have been cut at least once. The last time the were cut, there was .040 taken off. We now have a pushrod/ valve geometry/ lifter problem. We have ruined two sets of pushrods, just firing it up after initial adjustment I need to know how sells a pushrod tool to get the correct length on the push rods.

Thanks,

Bill
