engine valve train noise

Just fired my rebuilt 355 (seems to make great power) 9.75 comp, 64cc non stock performance vortec heads W/550 lift springs, 700DP holley carb, dual plane air gap manifold and a lunati #60103lk voodoo cam 268/276 489/504 and stamped steel 1.5 roller rockers, now the problem, the engine makes all kinds or valve train noise, I heard this cam is a little loud due to the valves closing at a high rate and I also heard the stamped steel rockers are noisy too, comments thanks XYZMAN

Re: engine valve train noise

Thats not a very big cam and it should not make noise. Check to make sure you adjusted the valves properly.
