Fresh 302, block was decked, valve train noisy

So the block was decked, the cam and lifter specs were changed, there's roller rockers, and for some reason the stock length pushrods?

Any one of those things can change the geometry enough to need a different length for the push rods, and we haven't even addressed anything done to the heads, valves or valve springs yet.

Those pushrods being the correct length has to have similar odds as winning the lotto, all the aftermarket parts and changes magically stack tolerances to zero so the factory length push rods fit? Not with my luck!
