Bought a “reconditioned” set of rocker shaft\rockers.. One set has washers on ends only... second set has several washers (not all) between rockers and stands. Is this the way it is supposed to be? Does anyone Disagree?
Thanks guys...You’ll likely need to dry fit the rocker assemblies on the engine and check that the pushrods are centered in the head holes for those. There are those people that prefer to center the rocker on the stem to make the rocker wear more evenly on the shaft. The oem design did not do this and instead relied on the extra long pad on the valve side to compensate for those variances in fit at the valves. Regardless of which scenario you are targeting for, it's a good idea that both engine banks do the same.Jack Groat (11/1/2020)
Question 2: Some half the rockers are ECG 6564 B2 and half are 5751066. These appear identical except for the adjuster bolt. I don’t see this as a problem. Does anyone Disagree?
Thanks guys... As long as you have eight of each, simply insure that the ECG rockers are on the same valves whether they are intakes or exhausts and the other rockers are on the opposing valves. My preference is to have the ECG rockers on the intake valves if I have a choice.
