Review on Bestong Camshaft Holding Alignment Compatible by John Kachinosky

Not worth buying, the Rotunda OEM tool works great even if the price is lower, the tool is useless and can damage the engine if you rely on it Tool holding the cams in place it pops out and the valves are clogged. Only use OEM, this isn't the only kit I've used from Revain that hasn't worked. Raven is great! It's just that some of the vendors that use them aren't good.
