Roller rockers can be a bit noisy sometimes. Honestly, your valve train sounds just like mine....like a sewing machine on steroids.:D


I wish they were roller rockers, but in reality they are the stock, stamped steel, rockers with cast aluminum pedestals that came off some stock Magnum heads (with cracks between the valves).

Even if it really isn't a 273 Commando engine with a solid flat tappet cam, I guesss it can sound like it.
