today I bought Comps Roller rockers : CCA-1322-16 SBM PRO MAGNUM STEEL 1.5 RATIO

Found the reason for the noise now. Different valve stem lenghts. Intake pushrods tight, exhaust loose. or vice versa, don't know yet. But it's now repaired and will get the heads tomorrow.

Can you guys imagine that the rocker set above does cost more than USD 87o.00 in Germany??? And that was a good over...
