We sometimes get what sounds like a noisey valvetrain on some engines. If we use aluminum heads, manifold and tall aluminum valve covers. The normal valvetrain noise seems to amplify through all the aluminum and the tall valve covers act like an echo chamber. We have found some roller rockers are noiseier than others. The blue proforms are very loud compared to a comp or crane. If the noise isn't a typical lifter ticking sound I would look elsewhere or the noise could be normal as we found.
